That reg doesn't apply to a landowner or family on their own land. Says so right in the part you copied. Only one person knows what that dog was doing when it was shot. There's not a German Shepard alive that can't get aggressive under the right circumstances. I am not saying people need to go around shooting people's dogs, but dogs need to be put up on your own property. This wasn't a hunting dog. Yard dogs that run loose are a dog hunters worst enemy public opinion wise.
