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.
Most dogs are right to be left alone for hours. It also just depends on the temprement of the dog, if it's a whinging dog & it crys the whole time you are gone well then you can't leave it alone but this is something you discover when you actually have the dogs. My dog is fine to be left alone for 8 hours while i'm at work.
