What I've been doing is tilting his head inward, and moving his hindquarters into the fence. It works for about, oh, a moment, then he's back to where he was. Normally I wouldn't be so frustrated, but my patience is wearing thing. He has made litterally NO progress even after 4 rides of me correcting him. He didn't do this in the round pen, but I bet it's because it's a small circle.
I've given up cantering him because every time I do he gets the wrong lead (obviously because he's crooked). I tried pulling his nose inward and lifting his shoulder and pushing him over before I canter him off, which works sometimes, but some of the time my cue (outside heel) pushes him back inward.
I'm thinking that it's not my riding. I've been known to have a stronger left arm/hand and keep the reins shorter on that side, but I've been very conscience of it as of late. Anyway, that would move his nose inward, not his hindquarters. If anyone thinks it is my riding, though, I won't be mad ;)
So, do you think I'm correcting it the right way? Any suggestions of excersizes to do that will discourage that? I was thinking theoretically that small circles might help since he has to move his his hindquarters outwards from his nose.
Thanks for reading, and any input you can give me. :)
