I have a 5 yr. Old Quarter Horse that definitely had potential as a barrel horse. Last year, when I had him trotting the pattern, he got tangled up in a gate and cut a little bit into his tendon on his left hind ankle. It took him months to heal up, and now he walks just fine on it. He trots around the pasture with no problems, that I can see. I saw him favoring it once, but I think my mustang ran him and made him jump the fence that day. I'm not seriously considering starting him on barrels again, due to his injury, but he had sooo much potential. I just need some opinions!
