Sorry about the misleading title, but I have a 2 (almost 3) yo mare that I just started working with under saddle (not much really). She has always been a dead-head. Really numb to everything. I have to actually hit her with the lung whip to get her to move in the round pen, I have had to use a rope halter on her to get her to listen better. It's not that she draggs me or whatever its just that when I stop to talk to someone she will take a few extra steps, small crap like that. Doesn't whoa "exactly" when I ask....stuff like that. She gets into everything. I like her personality but I put a broken snaffle in her mouth and I might as well have nothing on her. How do I soften her mouth up? She isn't disrespectful on the ground. I have worked with her on the ground to try to find something to go back to, but when I say "whoa" in the round pen, she plants it.
How do I soften a horses mouth that is naturally that way?
