So my brother has had this pony he's been riding for a while. He doesn't really like to ride and isn't a very good rider nor is he willing to learn. Now we adopted out a lot of our rescues and we only have four horses left (two who are rideable) My brother really likes this pony but he doesn't want to ride him. Now under the assumption my brother wasn't going to ride any more we sold all his saddle and helment. He knew this but thought that meant he was just going to ride in my sister's and my tack. So this pony we're fighting over was going to become my riding pony (when i say pony he's literally one inch from being a horse) I started working with this pony more and riding more often. Now my brother had no idea I was doing this (I thought he knew) so now we both want to ride this pony even though i love to ride and my brother hates riding. I've also been working on using my legs while riding him and teaching him whoa as when my brother rode him he'd only tug on his mouth. And I'm afraid if my brother keeps on riding him he'll ruin my work. I really don't know what to do and hoping you guys could help.
