Thank you all so much for your kind words. I don't quite know how to react - because "hero" was the furthest thing from my mind.

I posted this because it was so frightening - and most of all because I clearly do not understand why you would ever train a dog to attack another dog in a completely unprovoked situation. What is to prevent this dog from attacking one of their guests or God forbid a small child?

What frightens me most, is that I don't think this is going to be the end of this story.
