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.
You can end up with a dog that can never be left alone â ever! While my dogs are young (generally 2 years and under) I leave them crated whenever I am not home. I like to leave them with some projects to keep them busy, though I REALLY think they just sleep when Iâm not home.
