What's his name, by the way? And does he know his name? Think of him like a shell-shocked soldier home from the war, I would say it'll take a couple weeks before he truly begins to come out of his shell, so to speak. You can still work on housebreaking, but I'd just concentrate on that, and getting him to trust you right now. Poor thing has had his whole world turned upside down - he's probably still a bit dizzy, and doesn't know it is gonna last this time for sure.
