I would like to know what the safest and most effective way to put an end to rearing is. Instead of bucking, my STB mare rears. It's worse when she gets frustrated, or is taken away from the other horses. When I take her out for trail rides she'll try to turn around and run back to the barn, but if you pull on the reins to stop her she'll rear. So instead of using the reins to stop her, I've been pulling her around in a circle, but we usually just go round and round and then she gets frustrated and it just seems like a viscous circle. She's perfect when we ride in the field behind the barn. She relaxes, stops without a problem. My mum is selling her horse in the spring, which will leave us with only my mare and gelding. I'm worried that she'll become even more herd bound and her bad habit will become even worse. I plan to take her to some shows in the summer and fall, but because we will only have two horses, my gelding will have to come. I am concerned that she will not be able to function during classes if my gelding is not close to her. So I guess I have to two questions now. How do I stop her rearing habit, and keep her from being herd bound?
