I realize everyone has their opinions. I'm not positive on how tall it is, but I'll check next time. I don't plan on jumping him higher than that. He gets worked like that twice a week. He absolutely loves doing it. I really was trying to make him jump the part in the middle, but he didn't want to. I thought making it that high would make him not want to jump it. He's broken fences trying to jump them on his own, which was at least four feet. He loves it so I have him do it. He always jumps stuff. I'm not the type of person to push him more than he can handle. My barn owner knows a lot on bones and growth and she said it was fine as long as I don't jump him higher than that.
