I am currently riding a 5 year old sport horse mare who has recently developed a nasty habit of bolting. It has been going on for the last 3 weeks now and I am taking her to show 2 weeks from today. The first time she bolted it was unexpected when we were trotting passed a corner in the indoor arena. (She has been in the arena since she was a foal, it has not changed there were no noises or anything there). Suddenly she bolted to the left and I fell off. I got back on and she continued to spook until she calmed down when I got off. She bolted again when we were trotting a circle in the arena at the other half for no reason and this time when I fell off I hit my hip hard.
I believe she is doing it for attention now as she knows she can unseat me. This is becoming a big problem for me as my collection of bruises is growing as she is over 16.2 hh.
Please help! There are no warning signs, her body does not tense and her ears do not go foreward any more than usual.
***Saddle fit is not an issue here we had her saddle fitted to her and she is perfectly healthy***
