The thing is, every time I ask for a canter, he like shoots to the middle of the arena and does some weird thing with his hind. It's a big mess. I don't know what to do. I've tried inside leg, outside rein, asking from every gait, stopping and asking several times over. Nothing works. I don't know why he does this. And he has VERY bumpy gaits for being a plump QH.
He was trained for roping but he was a surprise and my hubby picked him out. He's been fine with English, but I don't know why he does this when he canters. He also has trouble staying on the rail at any gait, it's like I have to steer him to stay on the rail and then he bangs my leg against the rail a lot.
Any help would be great!
