You tube has video out takes of how he actually trains. It is not good. He kicks dogs on the side/underside where the area where the hip and stomach meet. I’ve seen it. Yes, I’ve know some dogs require physical correction. But to leave these clips out of his show is extremely misleading and wrong.
I think he’s a fraud. Just my opinion, though.
He doesn’t kick the dogs, just a surprise nudge. A hard one, yes, but not a full on abusive kick. It’s for surprise. This is not dog abuse.
