Very scary news. The most worrysome idea is that something might develope a little later for your mom, like a back or neck out of alignment. Although, if she feels ok today that is good news. Still, tell her to not sign anything from the insurance co rep for a while, they sometimes try to get that signature as soon as possible to avoid any later claims. As far as the dog, I had nearly the same thing happen to me years ago. Was in a minor fender bender, but shook my little dog up, and he crapped all over the seat. It's gonna be an especially happy Mothers Day for Ian this year!
