Wow! 2 Guard Dogs Bite Attacker

In this video Richard Heinz is showing how to utilize 2 trained protection dogs ( Dutch Shepherds ) to go and surround an Attacker by one protection dog guarding the front of the attacker and the second
protection dog to go around behind the attacker putting the attacker in a very uncomfortable and hopeless position.
Richard also demonstrates the absolute control an owner of protection dogs should have when teaching protection dogs this kind of highly complex training.
you'll see when the owner tells these 2 protection dogs to let go of the guy in the suit ( Richard Heinz ) that they both let go immediately. And when the owner calls them back from biting they immediately go back to the owner leaving the guy in the bite suit that the dogs were just attacking and would rather stay with than go back.
