The PDSA says dogs shouldn’t be left alone on a regular basis for more than four hours. Modern Dog Magazine says crated dogs shouldn’t be left home alone for more than three or four hours. PAWS Chicago, a nonprofit no-kill shelter, says five to six hours is the max for an adult dog. As you can see, there isn’t a specific amount of time experts agree on for every dog and your dog’s needs might change over time.
It’s imperative you take into consideration your dog’s breed, age, size, learned routine, established behavior patterns and health when deciding how long to leave him home alone. Some breeds, like Australian Shepherds and Siberian Huskies, need a lot of exercise and can become incredibly destructive if they are bored or left indoors. More than two hours alone could send energetic breeds into a frenzy. Basset Hounds are much more sedentary and relax well on their own.
Puppies are the most straightforward when it comes to determining their needs (fulfilling their needs, however, may prove to be the most challenging at this age). Basically, puppies need a lot of care and attention. Never leave a puppy under ten weeks old alone for more than one hour. This is primarily because they don’t know how to hold their bladders yet and because monitoring them at this age helps establish rules and boundaries. The American Kennel Club says when your puppy is between ten and 12 weeks old, you can work your way up to two hours. By six months old, most dogs can hold their bladder for about six hours. Senior dogs, on the other hand, will not only be able to go longer without a bathroom break, they’ll likely nap for more of the day than a young pup.
