Oh my, those poor women. They must have been terrified. Sounds as though the dog's owner was terrified, too. So glad that man shot the dog. Those are dangerous dogs, especially when the owner isn't a good dog trainer. The dogs are really territorial and don't stop an attack once they start.
At least that owner cares -- I was attacked by a German Shepherd that came flying through a door and ran out on to the sidewalk and bit me. The owner of that dog didn't give a shit, and didn't feel at all responsible. I wasn't going d2d, either, just walking down the street.
