Somewhere amidst all of the you're doing it wrong but said in a very positive and constructive way, I heard Chemaine Hurtado, owner and trainer at Symphony Dressage Stables, say something about opening the outside rein to move his haunches. It was as though I'd been hit with a stupid stick. Huh? was all I could think to say.
I kid you not. I do not know how to use my outside rein. Since we started doing both trot and canter half passes, I have been pulling my outside rein straight back in an obviously feeble attempt to get Speedy to move his haunches over.
And while I was solving that problem, Chemaine offered me one more little tip. In the trot half pass, when Speedy is finally bent and my outside rein is open, and he still can't quite get it, think about piaffe. If he can't keep the forward, he has to stay in that box I've created and still work hard. Piaffe is harder than just going forward. Even though it's not actually a piaffe, just by me thinking piaffe he has to work harder than if he just went forward.
