I no this may be a bit late but, iv had my pony now for over 10 years. We did a 5* vetting on him and the vet said his legs turn out but shouldn't cause any issues but they really have, we constantly have physio on him as it's cause of his legs rotating is due to his hips which causes his back to go and his legs compensate, because we never got X-rays or anything done we didn't no this would be the case for him. I would get him xrayed just to be safe because you could end up with a lame horse. I no a few people who have had horses for a few months and find out they can't ride them anymore because there's a underlying reason! I was young and just thought I wanted him and that was it, but I wish I looked more into it now! Xxx
