I bought my cutting horse at the end of October, and he had previously had his hocks injected a few months prior to that because he was getting sore..I've been told by my trainer and several people I ride with, that once they get them injected once, you will need to keep doing it periodically. We train year round, and I am planning on getting his hocks done in the next week or so, mostly because my trainer and a few other girls I ride with have said it would most likely benefit him before show season starts in March (and I have noticed him getting a little sore occasionally lately after a good work out..) Anyways, I've never owned a horse who has gotten hock injections, so just kind of wanted to hear from anyone who has experience with it..I hate to think about having to do this every 6 months or so (it's not cheap, and I've never really been one to treat a horse with medication unless apparently necessary)..Is this something I would probably have to continue doing for the rest of his show career or does it depend on the horse?
