You are just encouraging his bad behavior.

Show the dog that you are the pack leader and that is your space that he pees on. Claim it as your own and not his. What your dog needs is discipline. Walks where you control him. Times when he comes in the house and you set the rules as to where and what he can do. Never reward the dog with a treat or attention unless he has deserved it. A new member of the family "pack" can be confusing for a dog. The dog feels that his role has changed.
