Rocky Mountain Horses are not normally cow hocked. Their normal hind leg conformation should be straight with no deviation to the inside or outside. Click on this link to understand more about hind leg conformation. http://www.extension.org/pages/Relating_Form_to_Function:_Horse%27s_Rear...
Cow-hocked horses tend to be weak in major movements that require work off the hindquarters, such as stopping, turning, and sliding. This conformation can lead to swelling and lameness in the hock area.
