We have a horse out at the barn that has to be led with a nose chain at all times, so I do know how to use a chain shank and Olly hasn't reached that level of badness yet. :) He's not really endangering anyone with his behavior so I really hesitate to go to something like that, unless and until it becomes necessary but like I said, we've already seen a slight improvement in just a weeks worth of actual handling and demanding respect. He'll come round, and pretty quickly I think. I haven't tried carrot stretches yet, because with his disrespect issues he can get a little demanding with treats which sort of slows down the other progress, but maybe when he learns some manners we can work on it :) My question was, how do you keep his feet still when asking him to bend for the treat? Or to flex with the reins for that matter? I know sometimes you just have to follow them until they get it but he generally just goes into a spin for quite some time and doesn't yield at all.
