Defense Training

[Mirkawolf]

I wish you good luck, but my opinion is, you should not train defense with dog, who is not self-confident enough. He bites from fear, not from feeling any strong.
I think you should first teach the dog, that the incoming persons are no thread to him, to let them pet him or touch him and reward him for that. I´d only reward positive behaviour towards people from now on. I´d stop training any defense, unless it would be defense done in style of play - hunting the object (not the actual guy, but a toy etc.).
Once the dog is okay to go around and does not fear people in any situation, then I´d think about training defence, not earlier.
