As a veterinarian, I commonly hear that new puppy owners are alarmed by just how much a puppy sleeps. Dogs of all ages sleep more than us humans (lucky dogs, indeed), but the average number of hours puppies sleep a day is 16 to 18 â or even more.
It is normal for Pomeranian puppies to sleep 18 to 20 hours per day. Adults-Adult Poms (1 year and older) should be sleeping through the night, essentially mimicking their owner's sleep schedule. This gives them 7 to 8 hours to snooze. During the day, a few naps will be taken to bring the total hours of sleep to 12 to 14. Many dogs reserve their naps for when they are home alone. Seniors-It is common for dogs over the age of 8 years old to take an extra nap each day or to sleep slightly longer at night.
