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.
Well when a dog gets left alone for the day, he won't be too upset but if you keep doing that everyday, the anxiety builds up. Then if you go on a trip i would say that you need to have someone to come over and play with him for a while. About two days is a little long without anyone there. ShannonsBFF Â· 8 years ago.
