I'm a calm peaceful man so I can't say for sure what my response would be if this happened to my dog. I am relatively certain though that after I sat down and thought about it and let my initial anger pass that whatever reasoned response I gave would have to include a baseball bat in one capacity or another...
"When the snows fall and the white winds blow, the lone wolf dies but the pack survives." Winter is Coming Now this is the Law of the Jungle—as old and as true as the sky; And the wolf that shall keep it may prosper, but the wolf that shall break it must die. As the creeper that girdles the tree-trunk, the Law runneth forward and back; For the strength of the Pack is the Wolf, and the strength of the Wolf is the Pack.
