I don't rein...I like it, and I'm interested in it, but I don't think I'd ever be able to do it. Well, I was talking to my instructor about it, and she said that one lady she knows who reins teaches the sliding stop by running the horse into a wall. Not literally-you'd hope the horse will stop before it hits the wall, but I guess she points the horse there and runs them right up to it. The idea is to get the horse learning to stop correctly, but I'm failing to see the logic behind this. I guess it works for her, or else she wouldn't still be doing it, but wouldn't it teach the horse to stop only when it's being faced with a wall or fence? How would that apply if you asked the horse to stop in the middle of the arena? Can anyone explain this thinking to me? Is this the common way of teaching the stop?
