If it was the white knuckle part of the bone, I don't see how that could hurt her. If it was part of the bone itself, then that could be a problem. You shouldn't really have things like that available to her anyway. It's just their nature to get something like that if you get up. It smells too good to them. I would lose the shock collar. She will never totally trust you as long as you use it. There are lots of things that are said to be for use on dogs that small, but that doesn't make their use any less cruel.
