Then after lunch was the protection phase for those dogs that passed their obedience portion. It started with a simulated car jacking (or in this case, a truck jacking):
It's hard to see, but the handler and dog are in the vehicle when the "bad guy" approached and "asked for directions". Just as he was turning away, he came back and raised his left arm, which had a "hidden sleeve"- meaning the protective sleeve that the dog bites was hidden by clothing and was not visible as a bite sleeve. When the dog gripped the sleeve, he fired two shots (one low, one high) while yelling. When the judge (in blue) told him to freeze, the handler cued the dog to let go and the decoy moved away.
