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.
On average, between naps and full-on sleeping sessions, your furry buddy spends about 14 hours each day getting some shut-eye depending on his age, breed and activity level. If your barking chum is younger, heâll likely sleep around-the-clock, much like a newborn baby. Puppies sleep anywhere from 18 to 20 hours a day. Certain breeds, particularly large and giant breed dogs, tend to sleep extended periods of time, even as adults. So if you have a mastiff, Great Dane, Saint Bernard, Newfoundland or Great Pyrenees, donât be surprised if he spends 16 to 18 hours a day catching some zâs.
