I just bought a new horse, after my long search for a horse that would easily be able to do about 2 ft and work up to 3'9. So I've had him and I've been told he can jump pretty big from the amount of energy he has but I just talked to his previous owners (he was a lesson horse at a nearby barn) and I was told he can do about 2'6 easily but he's never really done anything higher than that. Im kind of freaking out right now because I was expecting to go higher with him. I would suppose he could go higher since he's a TB with enough energy to jump grand prix jumps but he's really green and has trouble staying staright to jumps and then gets crazy while jumping a course. Any advice
