I was riding my horse today and I tried to stop her by using the reins gently, and she stopped perfecty, but when I did it again she started running backwards, like literally trotting. So I started working on stopping, but she did the same thing every time, it is like impossible to stop her, and I have to jump off. She doesnt even look at where she is going, and she almost ran into a tree. I have never had this with a horse,what can I do to stop this and make her stop properly?
And why does she do this?
