I ride a horse for lessons sometimes, I am trying very hard to switch off of him because I am not enjoying paying for something I do not like to ride everytime. I am 5,3 and am transitioning from ponies into horses, this large pony is 14.2, 13 or so year old gelding. Not just to me, he is very angry and plain out mean, you go to get him from his stall he tries to bite or turn his behind towards you to kick. Very food savvy so will drag you into stall when he knows he has food. Abroad his back he is a nice ride but he tends to take over and runs through jumps home, always for the long one, and once he takes over one jump he will take over them all. Pins his ears when he sees tack and when you ride he almost always has ears pinned unless jumping. I enjoy hacking him, I think he likes it too, but when we jump in lessons him and I share an equal amount of disliking for it. What do you think the problem is?
