We just rescued a deaf puppy, he is a white pit bull. I have questions about training/commands. I know this will have to be silent training which i have never done before. Example: when he is biting too hard or too much do I walk away? tap him on his nose? When he potties do I get in front of him with a treat afterwards, pet him, how do I show my excitement for when he does good things and my disapproval for bad thing? I use "uh uh" and "yes" with my other dogs.
