It’s been 4 years since this post but…cowboy worked with him about 4 months. He never bolted with the cowboy b/c he could feel when things were starting to go sideways and derail it. He said if the rider tensed up at all, then yes, you’d get a bolt. He also rode bucking horses and said that he had a buck in him. I asked for an honest opinion at this point. Cowboy said this was not an ammy’s horse - you had to be on your game 100% of the time. Every day was re-teaching what you just taught him. Maybe a pro who loves projects.
I brought him home and tried some more. Yep, he bolted with me several times but not with the trainer. One day he bucked me off like a yard dart - out of the blue- trainer was there when it happened and didn’t see any reason he should’ve done it. I had a vet do yet another work up on him (we’d already gotten a EQ Saddle science due to the tiny mineralizations in the back muscle, no KS though). We’d xray’d the neck in the past with a different vet. A little C6/C7 but nothing to get excited about. A different vet chose to ultrasound the entire neck… then we found at C4 a deformed vertebrae.
Vet said maybe a job with a loose rein could work for him, maybe not.
I was super fortunate to find someone (after nearly 7 months of searching) that took him as a pasture pet - I still am in touch with them and he’s close enough for me to look in on. If I hadn’t found this person, I likely would’ve had to put him down or give up riding. I can’t afford two horses.
I hope your horse has a better outcome I am sorry you’re having to go through this.
Feel free to message me. This was a horse that you had evaluate very closely before even thinking about getting on - what is his body language telling me? What is his eye expression? The day he bucked me off, we probably missed a que because he was tense to get on at the mounting block. I should’ve gotten right back off.
