lol! Thanks Doggy, I had a feeling you'd be the first to respond xDDD
We've actually tried that, didn't affect them at all :/ They kept on chewing

They're just little terrors on four legs...
I'd try collars, but I'm so scared that they'd hurt themselves....we have a fenced, pretty heavily wooded 2 acres that they run a muck on most of the day.....and I'm afraid they'll get their collars caught on something and choke themselves :/
