Cracks are common of the Hoof. They can occur anywhere on the hoof surface, starting from the bottom of the hoof. Most of these are shallow cracks caused by dryness in the foot. The most common cause is damage to the outside layer of the hoof (periople) which normally prevents moisture from leaving the foot.

Proper care of the hoof will eliminate most cracks. This includes trimming and cross-rasping the crack. Some cracks do extend up into the Coronary Band and may cause lameness.
