Here is a picture of a Corn.   A Corn is a bruise located in the Seat of Corn, located in the Heel area of the equine hoof.  It’s a contusion, or impact injury that appears red, and pink in color.  Its causes are broad and vary but, it’s commonly a result of the horseshoe being too small or, the heels of the hoof left too tall creating excess pressure in the heel area.  A shoe that is left on the hoof too long can cause corns.   The hoof should be trimmed, every 4-8 weeks to avoid this type of injury.  Proper trimming includes trimming the hoof to maximize surface area and provide a large base of support.  When shoeing we should provide a platform for the hoof to grow into which is called expansion.
