I just bought a 3y/o 17h TB gelding who has stiff back hocks. He's only been off the track for 3 weeks now, and is currently on pasture board so that he is not standing in a stall getting stiff. However, his back hocks are still REALLY sore. I'm trying to determine if I should a) put him on joint supplements b) get him vetted/x-rayed c) do nothing for now and wait to see how he is in a few weeks/months. I don't mind giving him enough time to recuperate, and am in no hurry to get him on a riding schedule, since he's so young still. He does w/t/c and jump already, but you can definitely tell he's really super stiff in his back. I'm not sure if it's just because he was a racehorse (only raced 3 times b/c he was SO slow), and never had to use his hind end, or what, but I want to nip this hock issue in the bud sooner than later.
Any suggestion would be greatly appreciated!
