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.
As the body slows down and conditions like arthritis and hip dysplasia set in, dogs are far less apt to romp around the house or the yard. Typically, puppies sleep anywhere from 12-18 hours a day, adult dogs can sleep around 14 hours per day, large breeds may sleep up to 18, and elderly dogs can sleep even more.The noises and movements that dogs make during a nap seem to be clear indications that dogs do, in fact, dream.arge breeds sleep far more than small breeds. Itâs not uncommon for owners of Saint Bernards and Mastiffs to believe their dogs spend more time sleeping than they do in wakeful activities. A simple walk for a large dog can be enough to send the pooch into a two-hour nap.
