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.
Adult canines need between 12 and 16 hours of sleep, although it may vary slightly by body size, breed and other factors. Though 12 to 16 hours may seem like seriously significant rest to a human being, it is certainly a far cry from what puppies usually get.
