It is hard to teach old dogs new tricks and so one ought to start house training a puppy at an early age when he is most open to learning the correct actions and be taught how to co-exist with his owner. You will need to be patient as well as give your pet a lot of praise before it learns how not to soil the interiors of the house. No doubt, owning a pet can be rewarding and fun; but, you do need to train it so that it does not do its business inside the home therefore not only soiling your luxurious carpets, and furniture, but also leaving a evil pong that will be hard to get free off.
