How scary!!! I don't blame you at all for anything you did. I would have no doubt done the same, as would anyone. No one would stand by and let one dog hurt another, so DO NOT FEEL BAD.

I have no advice to offer, other than what you already know, to feed Arthur seperately. But I know you'll find a solution that will work for everyone. It can be difficult when one dog has issues like this. Best thing is to avoid it, but you know that.

I hope you and Charlie are ok. It was pretty scary just to read that, I can't imagine being there!
