separate his little dog from a pitbull that broke through his owner's fence and attacked the little dog.

Pitbull was shaking it around like a rag doll. I started kicking the pitbull in the nose for him to release but he would never release long enough for the kid to pull his dog away. At some point I stopped and told the kid he has to lift up his dog when the pitbull releases. It finally worked and the pitbull squared up to both of us. I thought oh boy here we go. But the pitbull was only interested in the little dog thank goodness.
