I remember that I always wanted to compete, over fences, with my Arabian gelding. Unfortunately, we were advised to give it up because he would cross his legs when he jumped, and frequently stumbled when he landed. We used to always joke that it was because he was from Polish racing stock, rather than jumping horses... but in all seriousness, is there any way to prevent this now or, if your horse does the leg crossing bit, do you have to just give it up as we had to, back in the day?
