No offense to Parelli people, but I think it's just goofy. I've been lunging him now, but every so often he'll stop, turn, and just stare at me. It's usually when I give a verbal aid or point the whip at him. It's a real ordeal to get him going again because he just stands there. It's annoying and lunging ends up being pretty unproductive. I know it's because he was trained to do that Parelli thing.
So, how do I get him to stop turning in? No matter what I do, he doesn't move a muscle. It's like trying to move a brick wall.
