Has he been neutered? If not, you could try getting him neutered, but, with that age, most likely, it won't do any good..The house is new to him, and he's marking it..You have to start from square one, just as if he would have been a puppy..treats when he goes outside and pees and poops and a lot of praise, and change your voice and let him know when he pees in the house that's not acceptable. If you don't catch him doing it, then you can't punish him later for it |
