 The deciduous teeth begin to erupt at 3 to 5 weeks of age, while permanent teeth usually begin to appear at around 4 to 5 months. All permanent teeth are present by the time the dog reaches 7 months of age (See table: Canine Adult Dentition ). Estimation of Age by Examination of the Teeth
In species with relatively short incisors, such as dogs, age determination of young animals using the teeth is only somewhat accurate and is mostly based on the time at which each tooth erupts. For the majority of large adult dogs with normal teeth and jaws, veterinarians can examine wear patterns on the teeth and give an estimate of age. Determining the age of small and toy breeds by examining the teeth is more difficult. For More Information

 If all the teeth show some tartar, and you can see worn places on the tops, she is around 3 to 5. A lot of tartar and tooth wear, along with pigment spots along the gums, tells you the dog is between 5 and 10, and heavy wear, missing teeth and a lot of tartar indicate she’s around 10 to 15 years old. 00:00

Tips
Dogs that have had good dental care might appear to be younger than they really are. Many factors, such as breed, can affect the accuracy of your age estimate. Giant breeds, such as Great Danes and Irish wolfhounds, age quickly and might not live past the age of 7 to 10, while toy dogs such as Chihuahuas age much more slowly. It is common for young tiny dogs to have bad teeth, because they are so often fed only soft foods, and tartar can quickly become a problem. Giant breeds might die of old age before they begin to show significant tooth issues, though a lot of wear on the incisors is not unusual. Warnings
Don’t let your fingers get caught in the dog’s mouth.

Each species of animal has its own unique type of teeth, depending on what type of food the animal normally eats. For example, a meat-eating animal, such as a cat, has quite different teeth than a grass-eating animal, such as a horse. However, all domestic animals have 2 sets of teeth during their lives, as humans do: a set of deciduous (“baby”) teeth that fall out, and a set of permanent teeth that develop later. Most dogs have 28 deciduous teeth and 42 permanent teeth. The deciduous teeth begin to erupt at 3 to 5 weeks of age, while permanent teeth usually begin to appear at around 4 to 5 months. All permanent teeth are present by the time the dog reaches 7 months of age (See table: Canine Adult Dentition ). Estimation of Age by Examination of the Teeth

Verify that she has all of her adult teeth, meaning that she’s past the puppy stage. If she has most or all 42 of her adult teeth, she’s around 5 to 7 months old. Once she reaches this point, the color and condition of her teeth, rather than the type or number, will give you an idea of how old she is. Step 6
See if her teeth are mostly white, or perhaps just a bit dull, with some yellowish tartar starting to build up on her back teeth. If so, the dog is about 1 to 2 years old. If all the teeth show some tartar, and you can see worn places on the tops, she is around 3 to 5. A lot of tartar and tooth wear, along with pigment spots along the gums, tells you the dog is between 5 and 10, and heavy wear, missing teeth and a lot of tartar indicate she’s around 10 to 15 years old. 00:00

 Chewing on bones and other hard toys or surfaces or fence fighting can prematurely break teeth. Also a diet based exclusively on soft food can accelerate tartar build up and tooth decay. The following guidelines can give you a reasonably good estimate of the dog’s age given that he has enjoyed a normal diet that includes kibble. At one year of age the dog’s teeth will be very white. The lower incisors will have ridges on top of them (the cusp) that resemble a fleur de lis design or that of a three leaf clover.

 Some detective work can help you estimate your dog's age in years or her stage in the canine life cycle. Step 1
Examine your dog's teeth. Typically, a puppy has a full set of baby teeth by the age of 8 weeks. These deciduous teeth are replaced by clean, white permanent teeth between the ages of 2 months and 7 months. If your dog is 1 or 2 years old, her teeth will start to be dull at the back, and might show some yellow discoloration. Between 3 and 5 years of age, a dog's teeth are typically somewhat worn, and tartar buildup may be evident. Teeth become significantly worn between the ages of 5 and 10 years, and beyond 10 years of age most dogs have worn teeth and significant tartar buildup. Missing teeth may be a sign of accident, injury or old age, but many dogs also are born with some teeth missing. Step 2
Observe your dog moving around the indoor or outdoor environment. If he moves stiffly and slowly, that is a sign that your dog is most likely in the second half of his expected natural lifespan.

Dogs’ adult teeth are usually all in by about six months of age. Before then, your vet can age puppies by their teeth (and obvious puppyhood) with extremely high accuracy. But once they’re all in, it gets tougher. Generally, dental disease, like tooth wear and loss, periodontal disease, and accumulation of dental calculus or tartar increases with age. But this is confounded by genetics: For example, small breed dogs tend to have more severe dental disease than large dogs. Regardless of size, some dogs accumulate tartar very young whereas others are tartar-free into their senior years. It is also confounded by behavior: in a past life, did your pup chew on bones, or rocks? But depending on the dog, teeth can be a valuable piece of information (and give me an idea of whether your dog might have a cleaning in his or her future).

 We can see a wear or scratching of lower central incisors, which will begin to show a more square shape. From 3 to 4 and a half years: their 6 lower incisors will become square, mainly due to wear. From 5 to 6 years of life: the wear of the upper incisors by the scratching will be evident, ours is in the years prior to old age. From the 6 years of life: you will see a greater wear of all teeth, there is more tartar and the fangs also become more square than pointy. They may also lose pieces, but it will depend on your dog's food and lifestyle. From this moment the dog prepares to enter their old age, which begins at the age of 7.

 Molars – Dogs do not have baby molars, but there are two permanent molars on each side of the top jaw (maxilla) and three permanent molars on each side of the bottom jaw (mandible). All molars will erupt by 4-7 months of age. Here is an image of an adult canine dental chart. Older Dogs
Vets use the amount of wear and tartar accumulation on your dog’s teeth to determine age when they are older. Dog teeth are typically less pointed after about 5-6 years of age. Your dog’s teeth will depend on their routine (how much they chew, what they chew, and food choice) and previous dental cleanings or at home care. This is why age is harder to determine after puppyhood. Breed ID Kit

 The adult premolars and molars come in between 5 and 7 months of age, erupting from the front of the mouth with the premolars to the back with the final molars. By 8 months of age, a puppy should have all of his adult teeth. 5 Indicators of Dog Age By Wear On The Teeth
The condition of a dog’s teeth can be an excellent indicator of his age. However diet, oral care or lack thereof, as well as behavior can affect your ability to properly gauge a dog’s age. Factors such a antibiotics taken while adult teeth are forming can affect tooth color from the start. Chewing on bones and other hard toys or surfaces or fence fighting can prematurely break teeth. Also a diet based exclusively on soft food can accelerate tartar build up and tooth decay. The following guidelines can give you a reasonably good estimate of the dog’s age given that he has enjoyed a normal diet that includes kibble. At one year of age the dog’s teeth will be very white. The lower incisors will have ridges on top of them (the cusp) that resemble a fleur de lis design or that of a three leaf clover. (

 3. Can you tell how old a dog is by looking at his teeth? The answer is, it depends. When dogs are young, you can estimate their age by observing which teeth have erupted. For example, a puppy’s deciduous incisors typically erupt between 4 to 6 weeks of age and the permanent incisors are in place by 12 to 16 weeks. The canines or “fang teeth” emerge at 3 to 5 weeks and the permanent canines by 12 to 16 weeks. By the time the permanent molars are present, the dog is 4 to 6 months old. In general, once a dog reaches six months of age, all or least most of his permanent teeth are visible. Once the adult teeth are in place by about 6 months, it’s anyone’s guess. I’ve known many veterinarians and dog lovers who claimed they could determine a dog’s age by gauging the amount of wear on the teeth.

 Normally, dogs develop all of their permanent teeth when they are about 7 months old. 1. If your pooch’s teeth are all clean and white, it is possible that he is about 1 year of age or younger. 2. Once you see a yellowish discoloration at the back of his teeth, your pooch may be about a year or two. 3. When a minimal tartar build-up is present and if some of his teeth wear off, he may already be about 3 to 5. 4. If your dog shows a more extensive amount of wear, as well as tartar presence on his teeth, then he may likely be anywhere between the age of 5 to 10. 5.

Understand how and why dog teeth wear down and decay. Tooth wear is a natural occurrence, but it can be accelerated by certain habits such as aggressively chewing on hard objects (bones, rocks, sticks) or in small dog’s without good dental care. On the other hand, some chewing is great for a dog’s dental health.

 Teeth grow fast at the early puppy stage. Because the change is so rapid, this is the most accurate time to be able to tell a dog's age. Count the type and position of your puppy's teeth to estimate their age. Newborn puppies are born without their teeth erupted from the gums. At certain intervals teeth will erupt. The first baby teeth to appear will generally be the canine teeth at 3-4 weeks of age. At 4-5 weeks of age the two middle incisors erupt. At 4-6 weeks the first two molars erupt. At 5-6 weeks the third incisors erupt. And at 6-8 weeks of age the third molar erupts.

If you’re wondering about a dog’s age, the condition of his teeth will give you a lot of information. The old expression, don’t look a gift horse in the mouth,is derived from the fact that horse’s teeth have distinctive wear patterns, that can help you determine his age fairly precisely for the first 7 years of his life and well beyond. Just as horses’ teeth provide strong evidence of their age, dog teeth have distinctive wear patterns that can help you to discern the age of your new family friend fairly accurately. 3 week old toothless puppy
How Many Teeth Do Dogs Have? Puppies should eventually have 28 deciduous teeth, 12 incisors (the small front teeth - 6 upper and 6 lower), 4 Canines (the fangs) and 12 premolars and molars. They are missing the first premolar and the last molars, that will eventually develop in the adult dog. The incisors are located along the front row of teeth, between the canines. Incisors are used in grooming and nibbling activities. The canines are used for tearing in conjunction with the incisors and premolars. The premolars follow the canines on the sides of the jaw;

 Dental estimates for dog years are based on the number and condition of a dog’s teeth and converted with the same ratios as above to dog years. Once a dog’s teeth have come in, puppies have 28 teeth in total. Fully grown dogs have 42 teeth in total. By the time a dog is seven months of age, all of his permanent teeth will have come in. A dog with a full set of teeth that are still bright white will be in her first or second year, and thus, depending on size, anywhere from 10 to 18 in dog years. Teeth that appear to have some use and yellowing, found in a mouth that exhibits the familiar odor we refer to as “dog breath,” in a fully-grown dog, may indicate an age in human years of three to five. This would put that dog along a spectrum of 29 to 45 years of age in dog years, again, dependent on the dog’s size, breed and overall health. It is much more difficult to estimate an age for an older dog, who may be experiencing tooth decay or missing teeth. With a mouth in that sort of shape, it is generally safe to assume, however, that the dog will be in excess of 10 human years, or between 64 and 80 in dog years, if not older. The condition of a dog’s teeth is a far less precise method for determining dog years than when you have a general marker of human years, along with size, as a basis for your estimate.

5 Indicators of Dog Age By Wear On The Teeth
Fooling the Experts With Good Canine Dental Care
 The new adult teeth should push out the rootless, deciduous milk teeth, although occasionally puppy teeth are retained. If the puppy teeth do not fall out on their own, they will need to be removed by a veterinarian to prevent them from affecting adult tooth placement and the dog’s bite. Starting around 12 weeks the incisors will begin to be shed and replaced with their adult counterparts. At 4 months the canines (the fangs) will begin to erupt. By 5 months, all of the adult incisors should be in place. The adult premolars and molars come in between 5 and 7 months of age, erupting from the front of the mouth with the premolars to the back with the final molars. By 8 months of age, a puppy should have all of his adult teeth. 5 Indicators of Dog Age By Wear On The Teeth
The condition of a dog’s teeth can be an excellent indicator of his age. However diet, oral care or lack thereof, as well as behavior can affect your ability to properly gauge a dog’s age. Factors such a antibiotics taken while adult teeth are forming can affect tooth color from the start.

 The canines or “fang teeth” emerge at 3 to 5 weeks and the permanent canines by 12 to 16 weeks. By the time the permanent molars are present, the dog is 4 to 6 months old. In general, once a dog reaches six months of age, all or least most of his permanent teeth are visible. Once the adult teeth are in place by about 6 months, it’s anyone’s guess. I’ve known many veterinarians and dog lovers who claimed they could determine a dog’s age by gauging the amount of wear on the teeth. Maybe. What if a young dog chews on hard things? That could lead to a three-year old stray dog mistakenly being categorized as a senior dog on the basis of worn teeth, resulting in a lower chance of adoption. Not good. I believe this myth of aging dogs by their teeth started with horses.

Determining A Dog’s Age

There are many reasons why it’s important to know a dog’s age. From the type of diet he should be eating, to what type of behavior to expect, and to determine if he is suffering a health problem or is simply getting older and slowing down. While it’s quite easy to tell a puppy from an adult dog, many fully grown dogs look a lot alike whether they’re 3 or 13. Fortunately, since our pups can’t speak up and tell us what year they were born, there are a few simple ways to make a close estimate of a dog’s age. Examine the Dog’s Teeth
Checking your dog’s teeth is the most common (and easiest) way to know how old he is. Normally, dogs develop all of their permanent teeth when they are about 7 months old. 1. If your pooch’s teeth are all clean and white, it is possible that he is about 1 year of age or younger. 2. Once you see a yellowish discoloration at the back of his teeth, your pooch may be about a year or two.

 For the next three months, there will be no noticeable changes. After five months, permanent teeth will start coming in, usually canines and molars first. By seven months, all permanent teeth will have grown in. If your puppy has all of its permanent teeth, then it is most likely more that 7 months old. Adult dogs will have around 42 teeth. After the puppy stage, age is marked by tooth wear. At one year, teeth are white and clean. By the end of the second year, the white will have dulled and tartar will begin building up. This will cause yellowing on the back teeth. After three to five years the yellowing will increase and be visible on all teeth.

 In total there are three pairs of incisors per jaw, and the final pair usually comes in at 5 months old. Permanent Canines – The adult canine teeth are visible starting at 4-6 months of age. Premolars – These are the teeth furthest back in your dog’s mouth before the adult molars erupt. The deciduous premolars are lost and four permanent premolars are added on the top and bottom of both sides. The permanent premolars come in between 4-6 months of age. Molars – Dogs do not have baby molars, but there are two permanent molars on each side of the top jaw (maxilla) and three permanent molars on each side of the bottom jaw (mandible). All molars will erupt by 4-7 months of age. Here is an image of an adult canine dental chart. Older Dogs
Vets use the amount of wear and tartar accumulation on your dog’s teeth to determine age when they are older. Dog teeth are typically less pointed after about 5-6 years of age.

 3. When a minimal tartar build-up is present and if some of his teeth wear off, he may already be about 3 to 5. 4. If your dog shows a more extensive amount of wear, as well as tartar presence on his teeth, then he may likely be anywhere between the age of 5 to 10. 5. Heavy tartar accumulation, severe wear, and missing teeth may suggest that your pooch is more than 10 years old, and may likely need older dog vet care. Looking at the Other Indicators
There are other signs that may give you an idea how old your dog is, too. These include his behavior as well as his other physical characteristics. 1. Study the dog’s nose.

Teeth are first thing you should check when trying to figure out your dog's age because a dog's teeth are a great indicator of their age. Puppies are usually fairly easy to spot, but their teeth can tell you what stage of puppyhood the animal is in. If your dog is an adult, his teeth can help you narrow down an approximate age. Your dog's permanent teeth will come in at around 5 months of age. The back molars are the last to come in at around 5-7 months. If your dog has all of his permanent teeth, you'll know that he is not a young puppy. At about 1 year of age, you will begin to notice bumps and ridges developing on the top of the front teeth. Between 3-4 years of age these bumps and ridges will be about 1/2 worn down. During this stage of life you will also notice tartar beginning to build up. Note:

 Once puppies reach 16 to 18 weeks of age they’re starting to get their first set of grown-up teeth: all of their 12 incisors, one set of four premolars and one set of four molars. Then from 20 to 24 weeks, they’ll get their four adult canines, three more sets of premolars and one more set of molars. Finally, at 24 to 28 weeks, their final set of two permanent molars erupts, only on the bottom. Overall, looking at a young dog’s teeth is a great way to tell his age — at least “in the absence of disease,” Casal says. “ There are diseases that will either delay tooth eruption or prevent tooth eruption, so those things make it a little bit harder,” she explains. “ But in general, if the puppy’s pretty much healthy, you can pretty much tell its age.” There are some breeds, however, that are more of a challenge. Casal finds that in “really tiny breeds ,” like Chihuahuas, “the teeth seem to erupt not as nicely as they do in other breeds of dogs, so it’s harder to see sometimes.” She added that in some dogs with underbites or overbites it can be harder for a vet to tell which teeth have emerged.

The last permanent teeth to come in will be the back molars, those come in between 5 and 7 months of age
Ridges and Unevenness on the Front Teeth: At about 1 year of age, a dog will have ridges or bumps along the tops of their 4 front incisors, top and bottom jaw. Front incisors are the teeth that your dog uses for that nibbling type of grooming. As he ages, the bumps will wear down. At 3 to 4 years of age, the ridges should be halfway worn away and at about 7 years of age, the tops of these incisors should be completely smooth. Tartar Buildup: Tartar generally starts to form around the teeth at about 4 years of age and gets darker and thicker the older your dog gets. Just like with people, tooth condition depends on genetics and dental care or lack of care. Tooth condition is not an exact indication of age, just a guide.

Like humans, dog hair will usually begin to whiten out with age. Areas especially affected include the hair around the muzzle and eyes. Note that this is a isn’t a particularly specific measure. Some dogs are born with a lot of white in these areas, or will whiten out much younger, especially wire-haired or furnished breeds. So take this with a grain of salt (and pepper!). Teeth
Dogs’ adult teeth are usually all in by about six months of age. Before then, your vet can age puppies by their teeth (and obvious puppyhood) with extremely high accuracy. But once they’re all in, it gets tougher. Generally, dental disease, like tooth wear and loss, periodontal disease, and accumulation of dental calculus or tartar increases with age. But this is confounded by genetics:

 The premolars do not appear until much later. At eight weeks and older puppies will have 28 baby teeth. At around 4 months of age the puppy will begin to lose its baby teeth as the adult teeth will erupt. Most times, puppies swallow these teeth but occasionally the owner will find a shed baby tooth or see the gum line is bleeding where a tooth has erupted. Just as with baby humans, puppies at this stage will love to chew on things! At 4-5 months the adult incisors, first premolar, and first molar will erupt. At 5-6 months the adult canine, premolars 2-4, and second molars erupt. Finally, at 6-7 months the adult third molar will erupt.

 If you have a puppy, it's fairly easy to determine its age by examining its teeth. Teeth start developing during a puppy's first year. The stage of teeth development is tied to a puppy's approximate age. At one month old, teeth will have just started pushing through the gums. At two months, a puppy will have a full set of deciduous (baby) teeth near the front of the mouth. At four months, adult canines and incisors will start to come in. By seven months, a puppy will have a full set of adult teeth and will have developed molars in the back of the mouth. When a puppy reaches a year old, you should notice ridges or bumps on both the lower and upper top front teeth. Keep in mind that teeth tend to erupt later in toy dog breeds. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/9\/97\/Determine-Your-Dog%27s-Age-Step-2-Version-2.jpg\/v4-460px-Determine-Your-Dog%27s-Age-Step-2-Version-2.jpg","bigUrl":"\/images\/thumb\/9\/97\/Determine-Your-Dog%27s-Age-Step-2-Version-2.jpg\/aid8850335-v4-728px-Determine-Your-Dog%27s-Age-Step-2-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"

 If your dog has all of his permanent teeth, you'll know that he is not a young puppy. At about 1 year of age, you will begin to notice bumps and ridges developing on the top of the front teeth. Between 3-4 years of age these bumps and ridges will be about 1/2 worn down. During this stage of life you will also notice tartar beginning to build up. Note: Keep in mind that dogs who chew aggressively have been abused or have dental health issues may have worn these bumps and ridges down earlier than the average dog. 2. Teeth Health
Tartar buildup on a dog's teeth will get thicker and darker as the dog ages. You will notice the brownish tartar build up on the canine teeth in the photo above. By the time your dog is 7 years old, the bumps and ridges on the top of his front teeth will be completely worn down.

Knowing your dog's age can help you anticipate any age-related health needs or problems. You can also have a rough idea of her remaining life expectancy. Beyond the first year or two of life, the saying about a dog year equating to seven human years holds roughly true: A life expectancy of 70 years for a human or 10 years for a dog is quite common. If your dog was abandoned, rescued or found as a stray, you may have no reliable records or documents stating her age. Some detective work can help you estimate your dog's age in years or her stage in the canine life cycle. Step 1
Examine your dog's teeth. Typically, a puppy has a full set of baby teeth by the age of 8 weeks. These deciduous teeth are replaced by clean, white permanent teeth between the ages of 2 months and 7 months. If your dog is 1 or 2 years old, her teeth will start to be dull at the back, and might show some yellow discoloration.

By the time your dog is 7 years old, the bumps and ridges on the top of his front teeth will be completely worn down. If the top of a dog's front teeth are flat, he is probably well into his adult years. Cracked or loose teeth is another sign of aging in dogs. Just remember that these dental health problems could also be caused by poor nutrition, abuse or early onset dental disease so you would need to rule those out first. 3. Signs of Arthritis
Another sign that your dog is aging could be joint pain and mobility issues.

Understand how your dog's teeth grow in. Puppies generally have around 28 teeth. For the first two to four weeks, there are no noticeable teeth. Baby canines start coming in after three to four weeks. Baby incisors and premolars start after four to six weeks. By eight weeks, all baby teeth are grown in.

On the top of your dog's mouth there are two molars. On the bottom jaw there are three molars. The first one is larger than the other two. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/e\/e2\/Determine-Your-Dog%27s-Age-By-Its-Teeth-Step-2-Version-2.jpg\/v4-460px-Determine-Your-Dog%27s-Age-By-Its-Teeth-Step-2-Version-2.jpg","bigUrl":"\/images\/thumb\/e\/e2\/Determine-Your-Dog%27s-Age-By-Its-Teeth-Step-2-Version-2.jpg\/aid221385-v4-728px-Determine-Your-Dog%27s-Age-By-Its-Teeth-Step-2-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"

 Tartar buildup starts shortly after this. Most dogs will start to show wear on their incisors, the teeth along the front of their mouth, between 3 and 5 years. The wear on the teeth will gradually increase as your dog ages. Significant tartar build-up with evidence of gum disease (look for red, inflamed gums) can be seen after they are 5 years old. Missing teeth usually means that the dog is a senior and could use some dental care. The stage and condition of the teeth can help to give you a good estimate of your dog's age, but remember that there are many factors besides age that can affect their appearance including breed, genetics, chewing behavior, and history of dental care. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/e\/ed\/Calculate-Dog-Years-Step-4-Version-2.jpg\/v4-460px-Calculate-Dog-Years-Step-4-Version-2.jpg","bigUrl":"\/images\/thumb\/e\/ed\/Calculate-Dog-Years-Step-4-Version-2.jpg\/aid1338936-v4-728px-Calculate-Dog-Years-Step-4-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"

Assess your dog's size and growth. If your dog is continuing to grow, then he is less than 1 1/2 to 2 years old, depending on overall size. Small dogs have reached their full height and length by around one year of age, but large and especially giant breed dogs may take until they are 18 months to 2 years old.

 Between 3 and 5 years of age, a dog's teeth are typically somewhat worn, and tartar buildup may be evident. Teeth become significantly worn between the ages of 5 and 10 years, and beyond 10 years of age most dogs have worn teeth and significant tartar buildup. Missing teeth may be a sign of accident, injury or old age, but many dogs also are born with some teeth missing. Step 2
Observe your dog moving around the indoor or outdoor environment. If he moves stiffly and slowly, that is a sign that your dog is most likely in the second half of his expected natural lifespan. Just as humans commonly experience problems such as arthritis in later years, dogs' skeletons typically become weaker and stiffer as they age. However, a young dog may move stiffly or awkwardly if she has suffered an injury in the past. Step 3
Look at your dog's coat and skin. Like humans, dogs usually develop gray hair as they age. Normally this happens by the time a dog is around 7 years old, but some dogs may go gray at an earlier age.

How Old Is My Dog? 5 Tips for Determining Your Dog’s Age
 They have that irresistible cuteness factor and are smaller in stature,” says Dr. Michael Lund, veterinary staff manager at ASPCA in New York City. And they have obvious body characteristics, “like paws that are too large for their body size, excess and loose skin, a gangly look, and a more playful and mischievous attitude,” describes Dr. Virginia Buechner-Maxwell, director of the Center for Animal Human Relationships (CENTAUR) at the Virginia-Maryland College of Veterinary Medicine. The best way to determine the age of a puppy is by looking at their teeth. All of a puppy’s baby teeth should erupt between 3 and 6 weeks of age and their adult teeth should appear between 12 and 16 weeks of age at the front of the mouth and between 16 and 24 weeks toward the back. But how do you determine your adult dog’s age if you don’t know anything about her? “ As a dog ages, I often look for loss of vision and hearing,” says Dr. Raymond Bouloy, a board-certified veterinarian with Cypress Creek Pet Care in Cedar Park, Texas. “ Is there any loss of mobility or pain? Are there cracked, loose, or painful teeth? Is there loss of cognitive function? All these areas help me determine approximate age of my senior patients.”

Dogs age more rapidly than humans, with an average lifespan of about 14 years, depending on the dog’s size, health and lifestyle. While many people calculate a dog’s age in human years by multiplying their actual age in years by seven, this isn’t correct because a dog ages more rapidly in his early years than his later ones. Most breeds age at the same pace for the first five years of life, but smaller ones age more slowly than larger ones after this age and can live almost twice as long in some cases.. Here are five steps in determining a dog’s age…. Step 1
Estimate your dog’s age if you don’t know exactly when your dog was born. A dog’s age usually can be determined by the state of his teeth. A puppy gets all of his baby teeth by 8 weeks of age and permanent ones by 7 months, according to WebMD. A dog 1 to 2 years old has little tartar buildup, and a dog up to 5 years old has some wear and yellowing of the teeth. Dogs over 5 years old may have serious tartar buildup and dental disease. Senior dogs, over 10, may also show signs of graying fur, cataracts and joint disease. Step 2
Determine if your dog’s size is considered small, medium or large.

 It’s for this reason that using the “one dog year equals seven human years” calculation isn’t completely accurate. While the newer method we’ve shared is more accurate, it’s still difficult to place a general formula on the way dogs age – as this progression will not only depend on your dog’s size, but their breed and individual genetics as well. What are common signs of aging in dogs? Therefore, it can be helpful to look at physical and behavior clues to determine your dog’s age. For example, teeth can be a particularly useful indicator of your dog’s age. As PetMD explains, by seven months, all of your dog’s permanent teeth are in; by 1-2 years, they’ll be duller and might have some yellowing; and by 5-10 years, they’ll show wear and possibly signs of disease. Other indicators of your dog’s age, especially as they reach the senior stage, include: Graying hair
Poor eyesight, cloudy eyes
Trouble hearing
Stiff muscles and joints, arthritis
Lower activity level
Behavioral changes such as increased anxiety,
confusion, accidents in the house, irritability, etc.

 Teeth are a reliable measure of age whether your pup is a rescue or not. In fact, studying your dog’s teeth may be the most accurate resource when investigating how to tell the age of a puppy. Teeth are a particularly reliable way to determine a puppy’s age because your dog will lose all baby teeth before he/she is about 6 months old. However, not all dogs follow this typical progression. Your vet is an expert in predicting dog age using a teeth chart and should be used as a resource. This is especially useful during the transitional time when your puppy is losing baby teeth and gaining adult teeth. After all of their adult teeth are in, it’s harder to determine an age range by studying their teeth. If you’re generally interested in learning more about your pup’s teeth, the American College of Veterinary Dentists breaks down the nomenclature of teeth in your dog. Here is a summary of your dog’s teeth and when they erupt: Baby Teeth
Deciduous Incisors – The deciduous (baby) incisors will most likely erupt when your pup is 3-4 weeks old.

 Hence how many teeth do dogs have can also help you to determine dog’s age. You can guess the age by looking at the teeth as deciduous incisors of puppies erupt when the baby is 4 to 6 week old and permanent incisors when the dog reaches at the age 12 to 16 weeks. If you find permanent molars then the dog must have age between 4 to 6 months. The complete set of permanent teeth is fully visible when the dog reaches the age of 6 months. Can dogs regrow their permanent teeth? Dogs like humans have two sets of teeth baby teeth and permanent teeth. Baby teeth are shed and permanent teeth are developed when the dog is of 12 to 16 month each. Dogs are not so lucky like some animals like sharks who can regenerate permanent teeth after they lose permanent teeth. It is very important to take care of dog’s teeth, especially when they have developed permanent teeth because these teeth cannot be regenerated and dogs need them throughout their life. Brushing teeth have the same importance in dogs as it has in humans.

 At 3 to 4 years of age, the ridges should be halfway worn away and at about 7 years of age, the tops of these incisors should be completely smooth. Tartar Buildup: Tartar generally starts to form around the teeth at about 4 years of age and gets darker and thicker the older your dog gets. Just like with people, tooth condition depends on genetics and dental care or lack of care. Tooth condition is not an exact indication of age, just a guide. Fur: Fur color is not a great way to gauge age. Fur around the muzzle or under the chin can start turning grey as early as 2 years old. Premature greying in dogs does exist. Stress is considered a factor, and dogs that had a rougher start in life may go grey earlier.

 They start getting their permanent canine teeth, the longest ones, usually right at 6 months old, which makes this the easiest time to accurately age a puppy.

Assess the condition of the teeth. Between the ages of 1 and 2 years old, many dogs will start to show some yellowing on their back teeth. Tartar buildup starts shortly after this. Most dogs will start to show wear on their incisors, the teeth along the front of their mouth, between 3 and 5 years. The wear on the teeth will gradually increase as your dog ages. Significant tartar build-up with evidence of gum disease (look for red, inflamed gums) can be seen after they are 5 years old. Missing teeth usually means that the dog is a senior and could use some dental care.

 After that, using teeth to estimate age is tricky, she says. “ After all the permanent adult teeth emerge, they only change over time by accumulating tartar, stains, or other signs of disease. The rates at which these changes occur vary widely by dog face shape, breed background, diet, and the dental care that is provided.” After a dog’s adult teeth have erupted, there isn’t an accurate way of aging a dog based on their dentition, says Dr. Heather Loenser, veterinary advisor for the American Animal Hospital Association (AAHA). “ Well-cared for teeth in a 15-year-old dog could look healthier than a 5-year-old dog who’s been allowed to chew on hard toys.” There are exceptions. Lund says some young dogs can have tartar and plaque buildup on their teeth fairly early in life. “ But moderate to severe amounts of tartar and staining or broken teeth often lead us to rule dogs out of the youngest adult class if no other evidence for youthfulness is evident.” If you’re up to it, take a whiff of your dog’s breath. Buechner-Maxwell says older dogs tend to have particularly bad breath, “especially if their teeth have not received regular dental care and have significant gum or tooth disease.”

Teeth are first thing you should check when trying to figure out your dog's age because a dog's teeth are a great indicator of their age. Puppies are usually fairly easy to spot, but their teeth can tell you what stage of puppyhood the animal is in. If your dog is an adult, his teeth can help you narrow down an approximate age. Your dog's permanent teeth will come in at around 5 months of age. The back molars are the last to come in at around 5-7 months.

 So if a vet looks in the puppy's mouth sometime before 8 weeks of age, she's likely to be able to get a pretty good idea of how old the puppy is when she sees which teeth have erupted so far, says Casal. “Where it gets a little tricky sometimes in dogs is between 8 and 16 weeks. Once you’ve got all your deciduous teeth, nothing really happens overtly for those two months from 8 weeks to 16 weeks ,” Casal says. “ But you can generally look at the overall state of the puppy and say, ‘Is it close to teething or has it just developed its deciduous teeth?’ There’s a gray area somewhere in between.” Once puppies reach 16 to 18 weeks of age they’re starting to get their first set of grown-up teeth: all of their 12 incisors, one set of four premolars and one set of four molars. Then from 20 to 24 weeks, they’ll get their four adult canines, three more sets of premolars and one more set of molars. Finally, at 24 to 28 weeks, their final set of two permanent molars erupts, only on the bottom. Overall, looking at a young dog’s teeth is a great way to tell his age — at least “in the absence of disease,” Casal says. “

Super Senior Dog Indicators:
 Learn the canine signs of aging and it will help you make more appropriate choices in the type of care you give your dog. First let’s talk a little about aging profiles of dogs. Small dogs can live up to 16 years, medium size dogs 10 to 14 years and large dogs, like a Great Dane size, typically live 7 to 8 years. Large breed dogs stay “puppylike” for 24 months or more, compared to the usual 12 to 15 months for medium and small dogs. Puppies: It is easier to tell how old a puppy is than an older dog based on their baby teeth: At one month of age, milk teeth start pushing through the gums
Permanent Canine teeth come in around 5 months of age
The last permanent teeth to come in will be the back molars, those come in between 5 and 7 months of age
Ridges and Unevenness on the Front Teeth: At about 1 year of age, a dog will have ridges or bumps along the tops of their 4 front incisors, top and bottom jaw. Front incisors are the teeth that your dog uses for that nibbling type of grooming. As he ages, the bumps will wear down.

Learn the canine signs of aging and it will help you make more appropriate choices in the type of care you give your dog. First let’s talk a little about aging profiles of dogs. Small dogs can live up to 16 years, medium size dogs 10 to 14 years and large dogs, like a Great Dane size, typically live 7 to 8 years. Large breed dogs stay “puppylike” for 24 months or more, compared to the usual 12 to 15 months for medium and small dogs. Puppies: It is easier to tell how old a puppy is than an older dog based on their baby teeth: At one month of age, milk teeth start pushing through the gums

Understand the structure and organization of your dog's teeth. All dogs have four basic types of teeth: incisors, canines, premolars, and molars. These are found on the upper and low jaws, on both the left and right sides. The incisors are the small teeth running along the front of the mouth. Adult dogs have six incisors on the top and six on the bottom jaw. The two side incisors (next to the canine teeth) are a bit bigger than the middle incisors; on the top these also tend to stick out to the side a bit more. The canine teeth are located behind the incisors, one on each side for a total of four.

Note changes in teeth for an older dog. As a dog ages, their teeth change. Changes in teeth can help you assess a dog's approximate age. Ridges on the incisors change as a dog ages. By the time the dog is three years old, the ridges will have worn off the bottom incisors. By five years old, the ridges will have worn off the upper incisors as well. A small amount of ridges on the upper front four teeth indicate your dog is between three and four. By seven, a dog's teeth are completely smooth. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/c\/c6\/Determine-Your-Dog%27s-Age-Step-3-Version-2.jpg\/v4-460px-Determine-Your-Dog%27s-Age-Step-3-Version-2.jpg","bigUrl":"\/images\/thumb\/c\/c6\/Determine-Your-Dog%27s-Age-Step-3-Version-2.jpg\/aid8850335-v4-728px-Determine-Your-Dog%27s-Age-Step-3-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"

How to Tell the Age of a Puppy using their Teeth

Say cheese!! It’s time to discover how to tell the age of a puppy based on their teeth. Yes, it’s all about teeth today. We will discuss how veterinarians determine dog age using a teeth chart and share how your puppy’s teeth are the key to predicting their age. Often, adopted dogs are a mixture of multiple breeds, so it’s hard to use breed or predicted body size to estimate their age (of course you could use an Embark DNA test to find out his/her predicted adult weight and breed mix)! Teeth are a reliable measure of age whether your pup is a rescue or not. In fact, studying your dog’s teeth may be the most accurate resource when investigating how to tell the age of a puppy. Teeth are a particularly reliable way to determine a puppy’s age because your dog will lose all baby teeth before he/she is about 6 months old. However, not all dogs follow this typical progression. Your vet is an expert in predicting dog age using a teeth chart and should be used as a resource.

Dog Years to Human Years: An Inexact Science Dog Years to Human Years: An Inexact Science
Dog Years to Human Years: An Inexact Science
What are dog years vs. human years?
Factors for determining dog years
Dog teeth provide a rough guide
Learn more about your dog and aging on Dogster.com:
 Large dogs who have reached 14 human years are 88 to 108 in dog years. The ratios for small dogs are more like 12:1, for medium-sized dogs, 10:1, and for large dogs, 9:1, but even that is only roughly accurate for the first two years of a dog’s life. As you may have guessed, comparing dog years to human years is inexact at best, but these measures for the first couple of years offer more reasonable estimates than the well-worn 7:1 ratio passed down over the ages in the fireside cackling of so-called old wives. Dog teeth provide a rough guide
The second frequently cited factor in determining a dog’s age in human years is the appearance of a dog’s teeth. Assuming that a dog is well looked after, cared for, and fed properly, the following are rules of thumb. Dental estimates for dog years are based on the number and condition of a dog’s teeth and converted with the same ratios as above to dog years. Once a dog’s teeth have come in, puppies have 28 teeth in total. Fully grown dogs have 42 teeth in total. By the time a dog is seven months of age, all of his permanent teeth will have come in. A dog with a full set of teeth that are still bright white will be in her first or second year, and thus, depending on size, anywhere from 10 to 18 in dog years.

Did you know that it is possible to estimate the age of a puppy by their teeth? As we have shown, the teething process which dogs undergo present various stages of development and growth. This is why we can roughly calculate the puppy's age by looking at their teeth. For example, if a puppy is less than 15 days old, it probably won't have any teeth. However, after 3 weeks of birth, the upper canine and incisor milk teeth start to appear. They are thinner and more square than their adult teeth. When they are about to complete their first month of life, we can see the emergence of these teeth in the lower jaw also. If the puppy is about to reach 4 months of life, we can observe the eruption of their central incisors in both upper and lower jaws. This indicates their permanent dentition has already begun to appear.

 Puppies possess 28 baby teeth while human babies will have 20 deciduous or “baby” teeth. 2. When do dogs begin to lose their baby teeth? Puppies begin losing baby teeth around 12 to 16 weeks of age. By four months of age, almost all of a pup’s deciduous teeth have been shed and many of the permanent teeth have already erupted and are in place. 3. Can you tell how old a dog is by looking at his teeth? The answer is, it depends. When dogs are young, you can estimate their age by observing which teeth have erupted. For example, a puppy’s deciduous incisors typically erupt between 4 to 6 weeks of age and the permanent incisors are in place by 12 to 16 weeks.

 Are Dogs Capable Of Regrowing Lost Adult Teeth? Many dog owners aren’t sure if their dogs can grow their adult teeth if they lose them. Unfortunately, unlike creatures such as sharks, your furry friend can’t regrow any lost or damaged teeth. Just as in humans, loss of an adult tooth for dogs means they lose it forever – hence the need to take maintain good oral hygiene in your pets. Can You Tell a Dog’s Age By Looking At His Teeth? Telling a puppy’s age is pretty straightforward since all you have to do is observe which teeth have erupted. For example, a puppy’s baby incisors usually erupt at four to six weeks of age, while the permanent incisors take root in 12 to 16 weeks’ time. The canines usually emerge by the time he’s 3 to 5 weeks old, with the permanent canines appearing in 12 to 16 weeks – just like the incisors. By the time the permanent molars are fully established, the dog is 4 to 6 months old. This means that once a dog reaches six months of age, all if not all of his permanent teeth are visible.

Hence how many teeth do dogs have can also help you to determine dog’s age. You can guess the age by looking at the teeth as deciduous incisors of puppies erupt when the baby is 4 to 6 week old and permanent incisors when the dog reaches at the age 12 to 16 weeks. If you find permanent molars then the dog must have age between 4 to 6 months. The complete set of permanent teeth is fully visible when the dog reaches the age of 6 months.

Inspect your dog's teeth. Look at the stage and condition of the teeth. Determine what stage the teeth are at. Puppies will usually have all of their baby teeth by the time they are 8 weeks old and should have all of their permanent teeth by the time they are 6 to 7 months old. They start getting their permanent canine teeth, the longest ones, usually right at 6 months old, which makes this the easiest time to accurately age a puppy. If they have all of their permanent teeth and they are white and clean, they could be up to 1 1/2 to 2 years, but probably around 1 year old. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/1\/18\/Calculate-Dog-Years-Step-3-Version-3.jpg\/v4-460px-Calculate-Dog-Years-Step-3-Version-3.jpg","bigUrl":"\/images\/thumb\/1\/18\/Calculate-Dog-Years-Step-3-Version-3.jpg\/aid1338936-v4-728px-Calculate-Dog-Years-Step-3-Version-3.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"

Figuring out how old a dog is by looking at her teeth is more of an art than a science, but a close look can often give you a pretty good idea. It’s easier if she’s a young puppy, but the teeth on older dogs hold some clues as well. Step 1
Open the dog’s mouth so that you can see all of the teeth. Dogs that aren’t used to this may resist, so be prepared to stop and have a veterinarian do the checking if necessary. A dog that is uncomfortable might pull back forcefully, try to keep her mouth away from you, lick her lips a lot or tighten her jaw muscles. Dogs that are very upset might growl. Do not ignore these warnings. Any of these indicators mean it’s time to let the vet step in. Step 2
Look to see if she has puppy teeth, adult teeth, or a mix of the two.

How Old Is My Dog? 5 Tips for Determining Your Dog’s Age
By Paula Fitzsimmons
Shelter dogs don’t often come with a lot of history, which makes estimating their age a challenge. But having this information is essential to providing optimal care. “It can help determine the most appropriate time for preventive health protocols, such as vaccination and de-worming, and the best time to test for certain common diseases such as heartworms,” according to Gainesville, Florida-based veterinarian Dr. Brian DiGangi, senior director of shelter medical programs at ASPCA. It’s pretty easy to spot a puppy. “ They have that irresistible cuteness factor and are smaller in stature,” says Dr. Michael Lund, veterinary staff manager at ASPCA in New York City. And they have obvious body characteristics, “like paws that are too large for their body size, excess and loose skin, a gangly look, and a more playful and mischievous attitude,” describes Dr. Virginia Buechner-Maxwell, director of the Center for Animal Human Relationships (CENTAUR) at the Virginia-Maryland College of Veterinary Medicine. The best way to determine the age of a puppy is by looking at their teeth. All of a puppy’s baby teeth should erupt between 3 and 6 weeks of age and their adult teeth should appear between 12 and 16 weeks of age at the front of the mouth and between 16 and 24 weeks toward the back. But how do you determine your adult dog’s age if you don’t know anything about her? “

Evaluate a puppy's age by assessing its tooth growth. Teeth grow fast at the early puppy stage. Because the change is so rapid, this is the most accurate time to be able to tell a dog's age. Count the type and position of your puppy's teeth to estimate their age. Newborn puppies are born without their teeth erupted from the gums. At certain intervals teeth will erupt.

Introduction
Fangs for grabbing and puncturing, incisors for nibbling, premolars for tearing, and molars for crushing bone -- although the family pet is far more civilized than his wild relatives, he still has the same equipment for eating, grooming, greeting, and defense. Like humans, dogs have two sets of teeth in their lives. The 28 baby teeth erupt through the gums between the third and sixth weeks of age. Puppies do not have to grind much food, so they do not have molars. Puppy teeth begin to shed and be replaced by permanent adult teeth at about four months of age. Although there is some variation in breeds, most adult dogs have 42 teeth, with the molars coming last, at about six or seven months. The order of tooth replacement is incisors first, then canines (fangs), and finally premolars. The teething period can be frustrating; the puppy clamps his mouth on everything he can reach, from body parts to Johnny's $80 sneakers, in an attempt to relieve the discomfort.

Just as we do, dogs have only two sets of teeth—baby and adult, says Creevy. In humans, the adult teeth begin to emerge in late childhood and early adolescence. In dogs, this occurs in the first six months of life. After that, using teeth to estimate age is tricky, she says. “ After all the permanent adult teeth emerge, they only change over time by accumulating tartar, stains, or other signs of disease. The rates at which these changes occur vary widely by dog face shape, breed background, diet, and the dental care that is provided.” After a dog’s adult teeth have erupted, there isn’t an accurate way of aging a dog based on their dentition, says Dr. Heather Loenser, veterinary advisor for the American Animal Hospital Association (AAHA). “ Well-cared for teeth in a 15-year-old dog could look healthier than a 5-year-old dog who’s been allowed to chew on hard toys.”

 Maybe. What if a young dog chews on hard things? That could lead to a three-year old stray dog mistakenly being categorized as a senior dog on the basis of worn teeth, resulting in a lower chance of adoption. Not good. I believe this myth of aging dogs by their teeth started with horses. Horses’ teeth erupt over a five-year period ("full mouth at five"), wear at somewhat established rates and you can get a ballpark guess of the age of a horse by careful examination of teeth. The same isn’t true for man’s best friend. Or man. Guessing a dog’s age must include much more than simply the current state of his teeth. 4.

 At four months, adult canines and incisors will start to come in. By seven months, a puppy will have a full set of adult teeth and will have developed molars in the back of the mouth. When a puppy reaches a year old, you should notice ridges or bumps on both the lower and upper top front teeth. Keep in mind that teeth tend to erupt later in toy dog breeds. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/9\/97\/Determine-Your-Dog%27s-Age-Step-2-Version-2.jpg\/v4-460px-Determine-Your-Dog%27s-Age-Step-2-Version-2.jpg","bigUrl":"\/images\/thumb\/9\/97\/Determine-Your-Dog%27s-Age-Step-2-Version-2.jpg\/aid8850335-v4-728px-Determine-Your-Dog%27s-Age-Step-2-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"

Note changes in teeth for an older dog. As a dog ages, their teeth change. Changes in teeth can help you assess a dog's approximate age. Ridges on the incisors change as a dog ages. By the time the dog is three years old, the ridges will have worn off the bottom incisors.

 Telling a puppy’s age is pretty straightforward since all you have to do is observe which teeth have erupted. For example, a puppy’s baby incisors usually erupt at four to six weeks of age, while the permanent incisors take root in 12 to 16 weeks’ time. The canines usually emerge by the time he’s 3 to 5 weeks old, with the permanent canines appearing in 12 to 16 weeks – just like the incisors. By the time the permanent molars are fully established, the dog is 4 to 6 months old. This means that once a dog reaches six months of age, all if not all of his permanent teeth are visible.

Dogs have two sets of teeth. Twenty-eight deciduous teeth erupt by six to eight weeks of age, and by the time puppies are six to seven months old these deciduous teeth are all replaced by 42 adult teeth. The permanent teeth include incisors, which are used to nip and bite; canines, which tear and shred flesh; and premolars and molars, which shear and crush. In short, a dog’s teeth serve as weapons and as tools for cutting or tearing food. The canines are the upper and lower fangs for which the dog family was named. As in most carnivores, the teeth are high-crowned and pointed, unlike the broad, grinding teeth of many herbivorous animals. Britannica Quiz

 Once a dog has its complete set of adult teeth, then that’s it. If a tooth is cracked or lost, it’s gone for good. That’s why good oral hygiene is essential, and brushing your dog’s teeth is a great idea. Can teeth tell me how old my dog is? Once your dog has all his adult teeth, it’s challenging to tell how old he is just by looking at them. With most owners aware of the need to look after their pet’s oral health, many dogs have very white and healthy teeth even into old age. After six to seven months of age, your dog will lose all their baby teeth and have a complete set of permanent teeth. As tooth condition varies a lot depending on diet and care, it’s unlikely that you will guess their age based on the state of the teeth alone.

 Each of his baby tooth roots generally becomes taken in by his emerging adult tooth, though there are times when this does not take place properly. At about three months of age, your pup will begin to lose his incisors in order to make room for the new teeth. When your pooch is four months old, his adult molar and canine teeth will start to appear. While the molars come in at the age of six or seven months, Fido’s complete set of new adult teeth emerge between the seventh or eighth months. What to Consider
As soon as your little pooch reaches the age of eight months old, he shall develop a total of 42 teeth. Some dogs, however, may have fewer or more. Generally speaking, the larger the breed, the quicker his teeth will emerge. To ensure that your Fido shows no bite problems, visit you vet by the time he’s three or four months of age. To offer your little buddy some relief while he’s teething, make sure to have plenty of chew toys available in differing texture and softness. Sometimes, a washcloth dipped in water and frozen can soothe sore gums, too.

How to Truly Determine a Dog's Age in Human Years How to Truly Determine a Dog’s Age in Human Years
How to Truly Determine a Dog’s Age in Human Years A puppy gets all of his baby teeth by 8 weeks of age and permanent ones by 7 months, according to WebMD. A dog 1 to 2 years old has little tartar buildup, and a dog up to 5 years old has some wear and yellowing of the teeth. Dogs over 5 years old may have serious tartar buildup and dental disease. Senior dogs, over 10, may also show signs of graying fur, cataracts and joint disease. Step 2
Determine if your dog’s size is considered small, medium or large. Small dogs weigh less than 20 pounds, medium dogs range between 21 and 50 pounds and large dogs are over 50 pounds in size. While most dogs age at the same rate until they reach 5 years old, after this age, larger breeds age more rapidly than smaller ones, affecting the calculation of the dog’s age in human years. Step 3
Calculate the approximate human age of your puppy by multiplying the age in months by 2 for puppies up to 5 months old. Puppies age very rapidly during their first year of life, especially during these first 5 months, a rate of growth which decreases as the dog approaches his first year of life. Multiply the age in months by 1.5 for puppies from 6 months old to 8 months old to account for the decreased rate of aging.

Look to teeth to determine a puppy's age. If you have a puppy, it's fairly easy to determine its age by examining its teeth. Teeth start developing during a puppy's first year. The stage of teeth development is tied to a puppy's approximate age. At one month old, teeth will have just started pushing through the gums. At two months, a puppy will have a full set of deciduous (baby) teeth near the front of the mouth.

Understand how and why dog teeth wear down and decay. Tooth wear is a natural occurrence, but it can be accelerated by certain habits such as aggressively chewing on hard objects (bones, rocks, sticks) or in small dog’s without good dental care. On the other hand, some chewing is great for a dog’s dental health. Rawhides or “dental” chews can help dogs break down plaque and material on the teeth. Also understand how disease manifests. By age three, nearly 80% of dogs will exhibit signs of gum disease. This can be seen in the buildup of yellow and brown tartar, inflamed gums, and bad breath. Gum disease is more prevalent in small dog breeds.

 Upon successful completion of the process, the permanent teeth pushes the crown of the milk teeth and finally they emerge into a permanent tooth. This entire process is referred as teething process and during this phase the Adults have the natural urge to chew different things, especially soft things. So, when you see your puppy biting different things during their growth period, then consider buying teething toys available mainly for dogs. These toys are soft to chew and even soothe their pain which is produced due to the eruption of permanent teeth. More about dogs teeth
You can also identify the age of your dog with their teeth itself. Every tooth of your puppy has a specific time period for its growth. For instance, the deciduous incisors are replaced within 6 weeks and the permanent incisors erupt within 12 weeks. So, when you see the incisors growing then you can guess that the puppy is about 4 months old. But this pattern automatically stops after they cross the age of 6 months because by that time the permanent teeth start appearing. After six months it would become difficult for owners to guess the exact age of the dog.

 By seven months, all permanent teeth should be in place. Step 3
Check the very back molars if the permanent teeth are all in. The molars will be very white and clean if the puppy is 12 months or younger. Between 12 and 24 months, the teeth begin to look duller and may have a little yellow tartar near the gum line. As the dog ages, there will be more tartar buildup on all of the teeth. If you see a lot of tartar and some wear, your Chihuahua may be between three and five years old. Between five and 10 years old, most dogs' teeth show wearing, heavy tartar and possibly signs of disease. Old dogs -- 10 to 15 years and older -- have heavy tartar, heavy wear and signs of disease. Some teeth may be broken or missing. Step 4
Look at your Chihuahua's overall appearance for more clues to its age.

My Puppy Has Two Sets of Canines | Cuteness My Puppy Has Two Sets of Canines
My Puppy Has Two Sets of Canines First come the incisors, followed by the fangs (which they use to grab and puncture food or objects) and then the rest. All of his baby teeth, 28 of them, should be in place by the time he's 6 weeks old. Adult Teeth
Around 3 months of age, adult teeth begin erupting. That's when that terrible teething stage begins -- when puppies chew on anything and everything and no shoes are safe. As the adult teeth come through the gums, the deciduous teeth should fall out. If a baby tooth doesn't fall out, the adult tooth may come in at a strange angle or an odd position. When the entire process finishes, at the age of 6 or 7 months, the dog has 42 adult teeth. Puppies don't have molars, used for grinding. Retained Teeth Issues
If retained teeth aren't removed, various problems ensue. Your dog might develop periodontal disease, since the presence of two teeth in the same spot causes food-particle collection.

However, some dogs (particularly toy and small breed dogs) tend to take longer to develop puppy and adult teeth. When puppy teeth do not fall out on their own and stay in your puppy’s mouth, they are called retained teeth. This is an issue that can lead to overcrowding, which can cause abnormal positioning of adult teeth and increased susceptibility to periodontal problems. Retained teeth are generally viewed as a genetic problem. It can happen in any dog but is more likely in small breed dogs. Your veterinarian will have to remove these teeth surgically to make room for the adult teeth. Number of Adult Dog Teeth
The age of eruption of permanent teeth in dogs is between 3-7 months of age.

 Food also plays a role in dog dental health. Dry food in strong chewers can help remove some plaque from the teeth slowing tooth decay and loss. There are specially formulated foods specifically for dental health. Your veterinarian can advise you on the proper diet for your dog if you are worried about its teeth. Water additives can also be used to combat teeth destroying and aging bacteria. Worn teeth can look fractured, though regular wear poses little health risk. Excessive wear can damage the root of the tooth, which can require a root canal. Part 2

Dogs are born without teeth but will grow two full sets of them by the time they are adults. Sometimes adult dogs don't lose all of their baby teeth when their adult teeth come in though and this can cause issues. Knowing what to watch for and whether or not veterinary intervention is warranted if your dog retains its baby teeth can help prevent bigger problems later on in your dog's life. Dog Baby Teeth
Dog baby teeth are also known as deciduous, milk, or puppy teeth and this first set of teeth starts appearing at about three to four weeks of age. At about one month of age, puppies have 28 baby teeth and they will have these teeth until their adult teeth come in and push them out. Baby teeth are not meant to be permanent and should fall out when the adult teeth arrive between three and a half and seven months of age. Dog Adult Teeth
Dogs have 42 adult or permanent teeth that should replace the baby teeth by about seven months of age. Puppies will begin teething at about three and a half to four months of age and will chew on items to help relieve the discomfort of the erupting adult teeth and loosen the baby teeth. As the adult teeth come in, the baby teeth are usually loosened and fall out on their own.

 Every tooth of your puppy has a specific time period for its growth. For instance, the deciduous incisors are replaced within 6 weeks and the permanent incisors erupt within 12 weeks. So, when you see the incisors growing then you can guess that the puppy is about 4 months old. But this pattern automatically stops after they cross the age of 6 months because by that time the permanent teeth start appearing. After six months it would become difficult for owners to guess the exact age of the dog. An Adult Dog has total of 42 teeth and when they are puppy they only have 28 teeth. Their teething process starts when they are about four months and it ends by about 6 months.

 When this happens, the puppy usually presents with a more intense pain than can be expected. Displacement of the tooth can occur. These leads to difficulty in chewing food and consequent digestion problems. It can also cause wounds and inflammation of the gums (gingivitis) due to inadequate growth of the teeth. Therefore, if your dog does not get their teeth or you observe injuries during this process, don't hesitate to consult a veterinarian. In many cases, a small surgical intervention may be necessary to properly detach the temporary piece of tooth and allow the full development of the adult tooth. How to know the age of a dog by their teeth
Did you know that it is possible to estimate the age of a puppy by their teeth? As we have shown, the teething process which dogs undergo present various stages of development and growth. This is why we can roughly calculate the puppy's age by looking at their teeth. For example, if a puppy is less than 15 days old, it probably won't have any teeth.

How Old Is My Dog? 5 Tips for Determining Your Dog’s Age
 Lund says it can be a huge help in estimating ages for middle-aged and senior dogs. Lenticular sclerosis shouldn’t be confused with cataracts, a serious condition that can lead to blindness, which is also marked by a cloudy lens. He says that most often, teenage dogs start showing signs of incomplete cataracts that typically progresses to complete cataracts. But not all dogs with cataracts are older. Lund says some breeds—including Boston Terriers, French Bulldogs, and Staffordshire Bull Terriers —are predisposed to juvenile cataract formation at a very young age, before they are 2 years old. Cataracts can also develop because of disease (e.g. diabetes) or eye injury. “ But being quite rare, changes in the lens are oftentimes a great aid in picking a much more accurate age estimate.” Previous

Freezing diluted chicken bouillon in an ice cube tray and allowing your puppy to chew on the frozen cubes. Providing safe chew toys that are too large to swallow. By the time your puppy is about 4 months old, the pressure from the adult teeth begins to dissolve the roots of the baby teeth and causes them to fall out. You will probably never see baby teeth lying around because your puppy will swallow them as they fall out. Adult Dog Teeth
At about 4 months of age, your puppy will begin to lose his puppy teeth and replace them with 42 permanent teeth (this number can vary with some breeds of dog) by about 6 or 7 months of age. This new permanent set of dog teeth will include: Incisors – 12 total (6 on top, 6 on the bottom)

What are dog years vs. human years?
Factors for determining dog years
Dog teeth provide a rough guide
Learn more about your dog and aging on Dogster.com:
 In these estimations, dogs are grouped into broad size categories, to wit, small, medium, and large dogs. Small dogs tend to have the longest lifespans, so estimations for dog years in small dogs generally see them age slower in dog years. Calculators still show variance when it comes to approximating dog years. At age 14 in human years, the calculators and charts we’ve consulted estimate that small dogs will be 72 to 84 in dog years. A medium-sized dog at 14 human years ranges from 78 to 96 in dog years. Large dogs who have reached 14 human years are 88 to 108 in dog years. The ratios for small dogs are more like 12:1, for medium-sized dogs, 10:1, and for large dogs, 9:1, but even that is only roughly accurate for the first two years of a dog’s life. As you may have guessed, comparing dog years to human years is inexact at best, but these measures for the first couple of years offer more reasonable estimates than the well-worn 7:1 ratio passed down over the ages in the fireside cackling of so-called old wives. Dog teeth provide a rough guide
The second frequently cited factor in determining a dog’s age in human years is the appearance of a dog’s teeth. Assuming that a dog is well looked after, cared for, and fed properly, the following are rules of thumb.

 Regular dog dental care is recommended by veterinarians, but few pet owners actually brush their dogs’ teeth. According to a study conducted by Ipsos, just 7 percent of dog owners polled reported brushing their dog’s teeth daily. “Just as with people a hundred years ago, we used to think that tooth loss was a normal aging change,” says Dr. Milinda Lommer, a board-certified veterinary dentist who practices at Aggie Animal Dental Center in Mill Valley, California. “ Now we know that tooth loss is the direct result of a disease process and it is not normal.” To better understand how to care for dog teeth, it’s important to understand the makeup of dog teeth and how to best ensure dog tooth health.

Science of Dogs Losing Teeth
Just like humans, dogs have two sets of teeth throughout their lives. The first set are the puppy teeth (or milk teeth), which develop when your furry friend is around three to six weeks of age. These 28 puppy teeth are surprisingly sharp and your pup will no doubt put them to good use as they chew on everything they can wrap their jaws around. However, as puppies don't really eat much hard food, there's no need for any heavy artillery yet, such as molars to ground down their food. However, these puppy teeth generally fall out when pups reach around four months of age. This is perfectly normal and may even go unnoticed, as in some cases your pup might even swallow the lost tooth without any fuss. The junior teeth are replaced by 42 adult teeth which are meant to see your dog through to the end of their life.
