People like that sicken me.
& you can agree or disagree with me on this, the dog is prolly better off being put to sleep rather than stay out on a chain, have a owner like that, and get tormented with rocks. The owner deserves what he has coming to him as far as legal proceedings, but the woman and her son need some lessons themselves.
I dont think the name really would matter much to people on this board, like my older girl's name is Spider.. she isn't vicious or "deadly".. she was merley a Halloween puppy LOL. But I think in that situation, I'm willing to bet the name came from his owner's need to fullfil something in himself and have a "big bad ass" dog and name.
