There is a thing you need to know. EVERY TIME you back down when your dog acts like he will bite you are teaching him that his behavior WILL get you to back down. This means the behavior will escalate as he learns he can make you back off. So, to avoid that happening CHANGE THE CONVERSATION. Redirect the dog to something else.
