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.
A dog should not be left alone for more than 12 hours, so if there are times when you are not able to get home to take care of your dog, boarding him may be a viable option. A dog boarding service will provide the dog with a place to sleep, play outside, run, and eat.
