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.
How long does a normal puppy sleep? The amount of time spent napping varies from dog to dog and depends on the dog's age and personality. Counting little naps and longer snoozes, most puppies sleep from 18 to 20 hours a day. As your puppy ages, he will sleep less. Adult dogs sleep about fourteen hours a day. The various breeds of dogs also seem to have different sleep requirements.
