What I still don't get is why this person would fight this in the Supreme Court.

If my dog bit someone or another animal, i would voluntarily muzzle him until his agression can be dealt with professionally. Dogs are allowed one bite before legal action is taken against the dog and its owner. I would hate to be sued or worse, have my dog condemned to death because I refused to deal with his agression issues. Yorkies may be small but they are still dogs and if they have biting issues they should be muzzled like any other dog. I hardly think any judge, much less a Supreme Court justice would argue with that.
