Yay for Fuzz! I still think you did the right thing. There was no perfect solution in this situation, but you made the choice that best protects an animal that has no way of pretecting itself. The little girl may be sad, but she'll be fine. If you had returned the dog to that environment, it may not have fared as well.
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
