I adore OTTBs – heck, I even help my friend ride and reschool them for new homes here, and have one that was very fresh off the track when I got him. You’ve gotten some good general words of advice, and here are my ramblings.
Top 5 things to look at:
- BRAIN – if the horse is jumpy and spooky, it’s jumpy and spooky and won’t change. That may be OK with you, but know it to start.
1.5 FEET – just as important, and I’ve taken a bath on an OTTB with bad feet, so I’m picky here. Expect some bad angles, etc, but they shouldn’t be TOO flaky, the sole be TOO flat or thin, and they should be sound. IF you can, get a farrier to put hoof tester on, or take a small hammer and whack the side of the foot. whole bunch of reaction and I’d pass.
- LEGS – reasonable wheels are important. Pinfiring is usually nothing, as are splints. Ankle “jewelry” is more worrisome.
- FLEXIONS – not realiable, but with an OTTB somewhat useful. SOME response is probably OK, a lot and I’d pass.
- TWO LEADS – most have it, but not all. And while that my not be a biggie for you, I really hate that.
- REASON FOR SALE – If you can, find out why the horse is being sold. If it was running good then suddenly wasn’t, I’d be wary. Mine was actually part of the Penn National race fixing scandal of a couple of years ago. Personally, I like the ones that did win a bit – they seem to “wait” for their rider more, but they can be right quick…
As to the retraining…
Lunging can be a very good thing, but don’t expect the horse to have a clue how to do it. Many OTTBs have never been lunged and don’t understand what is being asked, so don’t just slap on sidereins and go. For some, it’s just easier to work them under saddle.
Expect a pronounced one-sidedness.
You may or may not have a “canter.” You may only have a “run.” Trot is also optional, so be prepared for some, uh, interesting riding. And lots, and lots, and lots of biiiigggg circles for a few months.
Social skills may be less than optimal. Most OTTBs are great about trailers, tying (here at least they tend to be crosstied), clipping, worming, temps, wrapping, bathing, etc. But as to how to socialize in a horse group they may have no clue.
They may be very picky eaters, esp with regard to treats. Cut up carrots and apples may work, but not always.
OTTBs are really great horses, but they can be difficult. It’s really important to be able to not punish them for forward, although that doesn’t mean they’re allowed to bolt off. They should come back quickly, but never make a fuss about forward. It IS what they’v been bred and trained to do.
Good luck!
