I have seen a well known 2X winner that was deeply game and had finished a dog simply walk away from 3 dogs he mixed it up with in a yard accident situation. Outside of the box is a totally different deal IMO. I had an old dog that I could call off of a cat if he was chasing one, and who ran around with a Cocker Spaniel and a Labrador on camping trips. When you stepped over a wall though, he would go with anything including a bitch. I wouldn't evaluate a dog in a yard accident situation, or any situation outside of 4 walls. On the flip side, how many have "killed one" in a yard accident that couldn't fight their way out of a paper bag in a real roll or show? Inconsistincies in yard accident situations flow both directions, and thereby hold little bearing on how I would feel about a dog.
