I think both the nieghbors sre to blame....I mean, I fell very, very ,very, very sorry for that poor Golden owner, but she should have been making sure that the dog didn't go off her property, although, I have made this mistake as well ( my dog wandering off our property).... And I think that the guy who shot the dog should have broken in it up much easier......by simple pulling them apart.... any responsible person would have done that as long as the dogs were not dangerous together.
