Horse trailering trouble?
So last night I was driving my mare to an arena to ride for the night. On the way there, I took a turn a little faster then a meant to, not fast enough for it to be dangerous at all. My sisters gelding was in the space next to her (three horse slant load). I'm not exactly sure what happened, but somehow she lost her footing and slipped/ fell underneath the divider slightly (her hip got scraped as she stood up and she broke the padding on the divider I'm guessing) and then she started kicking the back side of the trailer. It scared me and my sister because we thought one of the horses had gone down with the fuss she was making so we jumped out and checked on them. She was fine, except for the scrape and she was a bit nervous so we carried on. About 2 minutes later, she started kicking again. We jumped out again because we didn't know what was going on. She was fine and we calmed her down, took her for a little walk and moved the gelding to the very front so that there was a space between them. We went on our way and this happened at least 2 more times. Every time we went down a hill, on a corner, or over a bump, she just started kicking. (we found this out because the only way we could get her to safely travel was by having my sister ride in the trailer on the way back talking to her). I'm wondering, what can I do to fix this? My mom suggested breeding hobbles. Any suggestions would be so very helpful. Thank you!
