We just got our 10 week old male whom is half house broken, the problem we are having is that he pees right outside the door when we take him out, however no matter how long his walk is that is the only time he will pee until we return to the house and then the accidents begin….any suggestions oh why this is happening or how we can resolve this problem? We are his 3rd family in his short life and he was abused by his other two families.
