Wow, you have your hands full! My best advice is to never let your puppy do things you don't want him to, because once he starts practicing this behavior, it will be very hard to break him of it. We have an older AmBull and my puppy used to clamp onto her lips and pull them out like wings, lol. She was soooo happy that I wouldn't let him do this, and would take him away from her every time he started pestering. It's constant supervision, for sure. Good luck!
