Anybody who went to westerville north might know the german shepard that lived accross the street; who was released if you walked thru some guy's yard. It seemed like a full size dog and had speed, I held my ground swung my hay maker, connected and the dog was done. Between the dog coming at me and my ability to the throw a punch he couldnt avoid "he got knocked the fuck out". I feel i would win against any dog. Dogs have many limitations.
People do crazy things when life is in danger. Against most dogs i would like my life is in danger.
