So I bought a pretty big time jumper (3'6 courses at 5, yes I know... she is young) and she was pretty much crazy which is why I got her cheap, only a few people could ride her. So I took her back to dressage for about 7 months and I just recently started jumping her. I jumped her around a lot of cross rails and she was really good, not lame or anything. I didnt see her the day after and when I came out 2 days later my trainer said she wasnt tracking up with her left front as much as she was with her right front, I guess she was about 2 inches off or so. I didnt see anything and I am normally pretty good at that stuff. So I got on her and walked her around a bit and she seemed fine. She does have a history of mild lameness (maybe a 2) in her front left possibly due to some navicular changes so she gets injected and has been sound ever since. We buted her and put her back, a vet came out and said she was mildly off but nothing to really be worried about. She was very very slightly off for about 2 days and then she was perfectly fine. A week after I had 1 hour and 30 minutes lesson on her, collection, galloping, ground poles, a lot of canter, and she was always sound so I started to jump her again. I jumped her higher this time, the biggest fence probably 2'6-9 and she was happy to jump it, the lesson was probably longer and had a lot more cantering in it and harder turns. The next day she was very slightly off my trainer thought so she gave her a gram of bute about 15 minutes before I got on her and I walked her around. One of the ladies at the barn told me she didnt see anything and asked me to trot her, and still she saw no lameness. I was kind of questioning my trainer a bit, but she went to UC davis vet school for a few years so I trusted her. My trainer said she was sound the next day. So the lameness after jumping got better even though I pushed her harder??? I was confused, if the jumping was causing this, wouldn't it get worse? So a week later I took her to a show, 18inch jumper course and intro dressage test, her first show with me! (we got 1st!!! Yay!) The next day my trainer pulled her out and didnt se any heat or swelling of any kind and she was sound! I jumped her yesterday and im anxious to see what she looks like today... So, could it just be she is using different muscles? All my jumping trainers are not to worried about it and they think it might be soft tissue or she is gaining muscles, my dressage trainer thinks I shouldn't jump her anymore and that its her navicular changes? I really don't want to retire her to dressage even though she could go far in it because she is such a phenomenal jumper. I bought her as a jumper and she was doing that just fine at about 3'6 every other day sooooo... Is my dressage trainer over reacting? Help! Im sooooo confused! I will try and take a video of how she moves today and post it up her too. Thanks!
