The jump was a tiny (like 2 ft) square oxer. It was off a turn and we were cantering to it. I gave him a good approach but he was getting squirrely and got all crooked in his body and wanted to take off long but I rode him to the correct spot. He jumped really flat and funky and caught the poles with his hind legs. I got back on and trotted a few more fences (including the oxer) before calling it-my poor bum was too sore for much more.
What can I do to help stop this behavior? I should add he only does this when schooling at home. We can be schooling somewhere else or showing and he is way more focused on his job and less temperamental on knocking rails. He also only does this when I ride him, though the only other person who ever rides him is my trainer, and I think he's scare of her a little, as we all are ;) ANY tips would be greatly appreciated! TIA!
