My horse will be almost lazy on the flat, but as soon as we start jumping he gets really excited. He has had everything checked and is healthy, it's just a behavior problem.
Usually, we'll go over a jump and he'll take off. Sometimes he throws his head down and bucks, or if we're outside, he TEARS. In fact, I fell off yesterday and got a mild concussion (obviously I won't be riding again til at least Saturday).
This is definitely something where I need help from a trainer, but until then, how should I help fix this? His bit is fine when we jump inside (only that issue with throwing his head down and bucking), but should I try something else? I ride in a kimberwick.
