So I just bought my horse 4-5 months ago. I bought him thinking he was older than he really was. His lip tattoo was misread and instead of being 6 he’s only 4. I didn’t find out until almost 2 weeks after he was home. For the first 3-4 months, he was an angel. Everyone loved him. Super quiet. We took him to two shows and he didn’t bat an eyelash. There was even huge gust of wind (for the life of me I cannot remember what they are called) that knocked down some jumps and all the horses were spooking but him. He just stood there. He is an OTTB. Only jumping 2’. I injured myself a couple of months ago so he went from being ridden 5 days a week to…once every week maybe every two weeks by a couple of different people. This past month he started humping during the canter, bucking, and now bolting with bucking. Checked the saddle fit and it was fine. I was going to have chiro look at his back to make sure he is not sore.
But what can explain the bolting? At first it was just me “sitting the canter” so I assumed maybe he’s just sore and he really hates the weight on his back bc he doesn’t buck or bolt in half seat. But even trotting he just will be mellow then take off with his head way up in the air, then he’ll slowly lower his head lower and lower which makes me think he’s going to stop and buck. Being that im just starting back up again after injuring myself, I asked my trainers daughter if she can ride him and see if he does it with her (maybe he’s picking up on my nerves). Same thing if not worse. He bolted from one end of the arena to the other (which doesn’t sound like a long distance but still not something I want my horse doing) would stop buck then bolt. She would reprimand him, but now my confidence is shattered. Why would a horse randomly start bolting? He was known for his beautiful rhythmic canter and now…this. what are the best corrective actions? I went from riding my horse almost daily all alone in the barn on an early early morning, to being deathly afraid and unable to ride without someone present with me. I’m extremely discouraged.
