Water & Nutrients. Like humans and animals, plants need both water and nutrients (food) to survive. Most all plants use water to carry moisture and nutrients back and forth between the roots and leaves. Water, as well as nutrients, is normally taken up through the roots from the soil.
Changing from puppy food to adult food depends on the size of your dog as an adult. If he is a small breed and will not exceed 30 pounds, he is mature at 10 to 12 months old. Some small breeds are mature before 10 months of age. Medium breeds are dogs that do not exceed 80 pounds at full growth.
Dog's Age. Many people consider a puppy an adult at approximately 12 months of age. Unfortunately, though, most breeds don't fall into a cut-and-dry pattern. Small breeds tend to mature physically around 8 months of age, medium-sized breeds around 12-14 months and large breeds around 18 months to 2 years.hen you determine it's time to make the switch, do so very gradually. Reduce the amount of puppy food you're feeding a quarter of a cup at a time while stirring in equal amounts of adult food.
