GRAPHIC: #1: Don't fight if don't have to. #2: If have to, fight like this cat.
Brief video of a young child being attacked by an unprovoked dog on the loose, and defended by his family cat. By the way, look at the injuries, in featured pic above, inflicted by that not very large dog. Anybody want injuries like that on their face? Neck? Groin? On their wife? Child?
Imagine what a large dog could have done.
