I got a new barrel horse the other day (the pretty girl in my avatar). Whenever we purchased her we were aware she has a really old injury on her back leg. The hair has never grown back and it is still "swollen" looking, but it doesn't affect her anymore, and the vet gave her the okay to keep barrel racing. I guess I should note her age, she is twelve.
I noticed whenever she is walking around the pasture that the leg that has the old injury pops. It doesn't hurt her, and she moves it normally, and it doesn't do it under-saddle. Only when she is at a walk around the pasture. She has been out of work since last August, and I know that sometimes a horse out of work can cause a stifle to be really stiff.
I am wondering if I should worry. Like I said, it does't affect her and the vet gave her the okay to keep running, but it bothers me because I'm wondering if this could be an early sign of arthritis. I am going to start her on a joint supplement and really watch to make sure that there are no problems. Am I overreacting?
