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.
Start small. At first, leave your child alone for 30 minutes while you walk the dog. Gradually increase the amount of time to an hour. Over time, keep increasing the amount of time so that the child may explore his own comfort levels. Reiterate the rules. Your child must be clear on the house rules and on the expectations you have when he is home alone.
