Last winter my trainer and I decided to take my pony's shoes off. After a few months of jumping fine, he started refusing. We put his shoes back on, but he has been nervous about jumping ever since. We have gotten him to jump, but he has to look at each fence and smell it before jumping. It has been about 7 months and he still refuses most fences the first few times we attempt to jump it. We've looked at his back and his feet and they are fine. He is slowly making progress, but its frusterating!Do you know of any other way to encourage him to jump?
