The other day, though, I took her on a trail ride which had begun pretty nicely. We went on a quick loop around the hay field and she was a little worked up but still under control, and just as we were coming back to the barn we had to pass one of the pastures. Her worst enemy, a slightly evil mare who has beaten her up once, charged to the gate right beside us with her ears back. At the same time, someone came around the corner with the tractor and was heading up the same road we were on. And the barn manager appeared out of nowhere to take Diamond's favorite two colts, who were extremely rambunctious that day, out of another pen. This also began a joyful stampede with some other horses and chaos in general. Talk about sensory overload for a green horse!
Diamond's reaction was to squeal, spin in circles, buck, and try her very hardest to kick the enemy mare across the fence. This went on for a while before I could get her back under control and I had been so taken by surprise that I missed my chance to reprimand her. Honestly, I have never encountered a problem like that before and didn't really know how to tell her that behavior like that is absolutely not ok.
I thought I should consult with the horse forum on this. I want to know what to do so that if she ever does it again I can make it clear that it is not acceptable. I have already asked lots of people what to do if a horse even bucks and no one really had an answer for me. Someone said to stay on and continue like normal and they will stop doing it eventually. That can't be right; is it? Do you make them work really hard? I can't do that right now because at the moment Diamond is pretty out of shape.
Thanks in advance everybody. I don't really have any knowledgeable horse people to ask about things like this so the Horse Forum is a life saver (perhaps literally).
