I had an OTTB a few years back that didn’t know much but seemed pretty willing under saddle. Then one day I was riding him and he was doing just great - forward and light to the aids. We came around the short end of the arena it trot. I asked for left lead canter and he stopped and went vertical, just like that. NO warning, nothing. I grabbed some mane for balance and tried to take enough rein to turn his head, but he was flipping his head from side to side, so I let go of the reins entirely. After what seemed way too long he came back down. All I wanted to do was get off. Didn’t pick up the reins, put my leg on, nothing and before I could so much as get my feet out of the irons he was up again. Absolutely straight up and flailing those front legs and whipping his head side to side. I decided it was past time to bail, so I did. What I didn’t count on was that I would land between him and the wall. I hit my head on the wall, got a broken rib and some other injuries. Glad I was wearing a helmet since I received a pretty bad concussion regardless. If he had gone all the way over, I’d be dead. (Did I mention he was 17.1 and beefy for a TB?)
I had a very good trainer friend of mine ride him for a month. He never could get the horse to repeat the behavior under saddle. But then one day, he was working him in long lines. It had all gone well, I was watching and feeling pretty good about things. Then, no warning again, the horse is trotting along, trainer has made no changes in what he’s doing with the reins, nothing. Horse just slams on the brakes, goes straight up and this time he does flip all the way over. My trainer friend felt just awful but it wasn’t his fault. We got him untangled from the gear, on his feet again and put him away. We didn’t even have time to discuss whether I should try to continue with him or not before he was colicking severely.
Had the vet out, got that taken care of, but he said it was definitely a stress colic.There was nothing else wrong with the horse. No teeth issues, no other physical problems, just a switch in his brain that when flipped, sent him up.
I’m too old for that sh**. Never again.
