House training a puppy or adult dog may seem daunting, but almost any dog can be trained to wait at the door and relieve himself outside, instead of going in the house. Create a schedule for feeding your dog and taking him outside. Then, reward your dog with treats and praise when he relieves himself in the designated outdoor spot. When he makes a mess in the house, just clean it up and stick to the routine, since punishing a dog will simply make him afraid of you. Patience and a good sense of humor are all you really need to help your dog adapt to life as a pet.
