I think the decision on what to do with Rufus ought to be your daughter's decision, and only made in a few days or a week's time, so she can see past the emotions. Just my opinion, but thought I'd give it to you to help you figure out how to deal with the vicious, albeit sometimes-tolerant dog. (That is Rufus in your avatar, right? Hard to stay mad at a dog willing to put up with that costume, even if he is a pet slayer.)
