I have a Quarter horse gelding who likes to jump, and I think he could jump anything you pointed him at. However, I'm fairly new to jumping and I've only jumped crossrails and small verticals on him. I'll usually set up a jump or two mainly for me to practice over. At the beginning of the ride he jumps great- really alert, doesn't knock or touch anything, just really good. I'll go over the jumps a couple times, go do something else, come back...then towards the end of the ride he gets really lazy and careless with it. He starts knocking them down, then he just practically crashes through them. Is he just bored? I would set up more jumps and make little courses, but right now I don't have much stuff to use as jumps (I'm working on that) and I just want to practice my position, but I can't jump anything if he's knocked it all down! How can I keep him clearing the jumps the whole time?
