[Buster Bailey]

This may sounds silly, but it was the only thing that worked for me...I read it online somewhere. Buster & Bailey were never really bad biters, but all puppies bite & have to learn boundaries. They are the same age & we got them when they were 11 weeks old (they're now 11mths old). If they ever bit me, I would immediately stop whatever we were doing, and storm off like a pouting toddler saying "You are a really big jerk <Bailey or Buster>, Ouch!" I guess since I was calling them a jerk, my voice actually reflected the appropriate tone or something like that. I felt was pretty silly (and actually kind-of bad for calling them jerks) because I really threw a few tantroms & tried to make them feel bad. It didn't take long before they figured out they were not supposed to bite human skin. I also tried replacing anything they bit that was bad with an appropriate chew toy (they always seem to find something they aren't supposed to have!). Good luck in your training!
