Do you do very strenuous work(ie reining jumping... Ect)
Cow hocks that are turned in more than slightly are a weakness and cause problems. A tremendous amount of strain is placed on the inside hock joint structures. Bone spavin is common. The pasterns and cannons also undergo an abnormal twisting motion that leads to fetlock joint strain and predisposition to injury. More weight is carried on the medial surface of the hooves, so corns, quarter cracks, and bruising are common. Also, the lower legs twist beneath the hocks when the hooves land, so interference injuries of the lower legs are possible. Speed is deterred since the cow hocks weaken the thrust generated from the hind legs.
