Dear god that is so awful. I'm very very sorry you had to see that happen. I once saw a video of a horrible act of cruelty to an animal which I won't talk about, but whenever I think about it, I feel like I'm going to get sick. I can't imagine really seeing it. That poor dog, at least you were able to get that woman away from hurting anyone else. Take it easy, and give your dogs a special hug for me. I hope you can rest better soon.
