Any suggestions for working on head tossing in a horse? Jayne does it whenever he's being pissy and doesn't want to do what you're asking him or is frustrated. No buck or rear, just head tossing/bobbing. He's always done it as long as I known him- it was one of the reasons he was sold to me. They rode him in a tie-down, and all that did was teach him he could only do it so high or low, not actually resolve the issue at all. He also does it while standing tied sometimes with or without pawing.
For me, he'll do it WHILE doing whatever it is that I'm asking that he doesn't like or doesn't really understand/know well, and it doesn't really bother me all that much since he's still doing what I want with his feet. Pain is unlikely since he's done it bareback, in different saddles, etc, and it only comes up when he's showing some attitude. If I smack him on the side of the neck or otherwise correct him, he'll stop for a while, so it's not been something I've really worked to correct on a regular basis.
BUT I know some other people see it as a serious problem, and I suppose if I was interested in showing, it would be. Any safe ways to correct it? Any ways to correct it so he's less likely to try it with other riders?
