Well, I don't have much advise, but I hope you stick with him. Obedience training can be taught with hand signals, which are almost as easily learned as vocal commands. Personally, I don't think it would be all that much more difficult to care for a deaf dog than a dog that could hear. Of course, there would be things that could be more difficult, like calling him to return, and puppy training. I read once that deaf dogs are less likely to stray, and stick around their home and owners. They are more clingy to their owners. I don't know if that's true in every case, it's just something I read in Bully Breeds magazine.
