Puppies need a lot of sleep because they are growing, and the AKC notes that older dogs also need more rest because they tire more easily. Healthy adult dogs usually sleep fewer hours than either group. Age also changes when your dog sleeps, with puppies napping often and seniors resting more through the day.
Dogs take many naps across the day and night instead of one long block like people. Short naps between activities are normal, even if your dog seems to sleep whenever things are quiet. This pattern helps dogs stay alert, because they can wake quickly when something happens.
A dog that has had a long walk or a busy play session may sleep more deeply, while a dog with little going on may simply rest more. See how often to walk your dog. Mental exercise such as training and scent games can tire your dog out too.
Breed, size, and temperament affect how much your dog sleeps. Some dogs are calm nappers, while others stay alert longer. Compare your dog to their own normal, not to other dogs. Ask your vet or breeder what is typical for your dog’s breed.
Dogs with little to do may sleep more to pass the time, and the AKC lists boredom among factors that affect sleep habits. See how to tell if your dog is bored and how to keep your dog happy and entertained at home. Adding variety to your dog’s day often helps.
Pain, illness, or an uncomfortable bed can change how much and how well your dog sleeps. If sleep changes suddenly, check with your vet. See how to choose the perfect dog bed. A dog that sleeps more while also eating less or moving stiffly should be checked.
