Any defect in a hoof wall is cause for concern. The action required, however, depends on the nature of the crack. Here is a list of hoof crack descriptions ranked---generally speaking---from least to most worrisome:

• Small, vertical cracks that start at ground level and extend upward an inch or less. These will typically be resolved with the next farrier visit and require no further action.

• Horizontal cracks an inch or less wide that originate at the coronary band and grow downward as the hoof does. Cracks like this are typically associated with a minor, healed trauma to the coronary band that briefly interrupted hoof production. As the hoof grows out, the crack migrates downward to eventually grow out entirely. Chances are no intervention will be needed during this process.

• Vertical cracks at the bottom of the hoof that continue around the bottom of the foot to affect the sole. You’ll need to pick up the hoof and perhaps clean it a bit to look for this. If the crack appears to involve any structures other than the hoof wall, it could become a more significant issue. Mention this to your farrier and veterinarian and keep a close watch out for signs that it may be more than just a superficial defect.

• Long, persistent vertical cracks.
