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.
If your puppy wants to sleep, let him sleep. Your puppy needs 18 to 20 hours of sleep a day. He'll get some of this sleep during the day in the form of short naps. You should establish a bedtime routine, however, so that as your puppy grows into an adult dog he learns to get most of his sleep at night.uppies need more sleep than adult dogs because they have a lot going on in their lives. Puppies grow and develop physically very, very quickly. They also have a lot to learn, and they're struggling to find their place in the family and the world. Puppies spend their waking hours learning all sorts of new things.
