What is a "fetlock"?

A fetlock is a joint located on the lower part of a horse's leg, between the cannon bone and the pastern. It is an important point of support and flexibility for the horse during movement. The fetlock joint consists of tendons, ligaments, and bones, allowing the horse to extend and flex its leg while maintaining stability. It is particularly vulnerable to injury and requires proper care and monitoring to ensure the horse's soundness and well-being.
