You guys are softies.
I caught my neighbor throwing rocks at my dog a few years back, and put an end to that right away. With a manly roar i yelled ' if i eveeeeeeeeerr catch you doing anything to my dog i will bust your fkn neck"

come to think of it, i haven't see them for a couple years now.

I have a neighbor right now who's dog barks alllllll th time non stop.....it is not the dogs fault. I looked over into the yard and the thing has his face pressed against the back door to let him in, or feed him, or communicate ! Something! I call them on the phone and make them know they are the bad guy.

However make sure you or the dog isn't at fault, but the blame comes back to you ! There is a gap somewhere in pet management. If not...i'd suggest some sort of posturing with a firm message.
