The horse I ride, Roly, is very good at jumps. That is when he decides to go over them. I haven't jumped him yet but. I've heard and seen people attempting to jump him. At pony club all the girls that have ridden him say he jumps big but only when he wants to. He will trot or canter towards the jump and then just stop right in front of it and refuse to jump. But then sometimes he jumps and he jumps big when he does. But any idea of how to make sure he doesn't continually refuse a jump? He's not scared of them just most of the time he doesn't want to jump and then sometimes he does?!?
