We had a big warmblood mare that could be a nightmare to ride. She was very spooky and didn't like to yield to the rider's aids. She was the one I fell off of four times... lol Well I fell off her a lot more than four times... She was a good jumper, though as long as she didn't spook at the fence and stop. Anyway, she was also very cranky and was known to bite and kick. Well, in the therapeutic program we had a group of autistic men come for lessons and I was short horses, so decided to use her. One of the guys started grooming her and pretty soon her head was just about on the floor, she was so contented. Anytime me or a volunteer came near her, her head would raise and her ears would go back. lol So we let them be and she was an absolute angel. Once he was mounted, this mare who was so unyeilding to our best riders took every step very deliberately, bent around the corners, and held herself in a perfect frame. All in a halter and reins. No bit. It actually brought tears to my eyes to see the change in this horse. My boss was watching from the lounge and I could see by the look on her face I was going to be in trouble for using this horse, but once she saw the transformation in the mare, I was applauded for using her. She turned out to be one of my best therapeutic riding horses. It's amazing how they just 'know'.
