How to treat (and prevent) corns.
Corns are bruises occurring at the angle between the hoof wall and the bars (see photo). They’re commonly caused by shoes that are too short and tight at the heels, or that have been left on too long (the shoe slips forward and the heel branches traumatize the area). Stones and hard surfaces can also be factors. Corns may be dry (mild bruising), moist (clear, watery discharge), or suppurative (infected or abscessed). Treatments include removing shoes, expert paring with a hoof knife to relieve pressure, and draining/poulticing as needed. Competent hoof care at frequent, regular intervals is the best preventive measure.
Corns occur typically on the soles of the front feet, at the “seat of corn” (areas indicated by the dots).
