When an animal is post-legged, the leg joints are far too straight, with almost no bend in the legs. Four-legged animals must have some bend in the hocks, otherwise the hooves would wear unevenly, and this may result in lameness, or at least a rougher gait. The animal will not stand squarely on the ground, and this also increases the possibility of injury to the animal. When an animal is post-legged, the animal will have a much higher risk of lameness, perhaps even permanent.
