For the health and well being, you should not leave your pet home alone too long. Adult dogs (those over 18 months of age) can be left alone four to six hours a day. Young puppies should not be left alone for long periods during the day â around two hours a day is the limit.
There is no breed or type of dog that does well left alone for long periods of time. Dogs are pack animals, meaning they have an instinct to live in a group. When humans bring a dog into their family, in the dogsâ eyes, there has to be a pack leader.
