Oh boy, I think you have a very smart pup on your hands. My only question is why does he have access to your floors when you are not around? I would keep him totally confined unless you are actively paying attention to him. Does the x-pen not have a bottom? How big is it? Maybe he needs to be crated when alone. Just suggestions. It's not forever, just until he knows what is expected of him.
