Taking a lifelong puller and re-training him to be a dog who pushes into the bite. The act of the dog pushing in makes the decoy submit or turn pressure off. This turns the dog into an active part of the fight instead of a dog who just hangs on for the ride with a shallow grip while the decoy thrashes about.
A satirical video of a K9 Pro sports competition. The satire comes from using the grandiose over the top marketing that is used to promote K9 pro sports.
Nothing personal against any of the competitors as anyone who does anything with their dogs should be supported.
