Regarding drive in training.. I got a dog of a man I met in a dogshow that trains his dog in personal protection and there is this instance that the target is on a running car.. the pitbull rank after the pickup and jumps but come up short head first. He is stunned but went back and finish it task. It's on quality that you can onyl find in a pitbull. I believe in that scenario if some doberman got that accident or beating.. he might just stood there.. it got a youtube vid.. I'll post later.. let me look for it first. hehe.
