A. While most hoof cracks are superficial and do not cause much pain, horses can become lame due to deep hoof cracks that reach the sensitive inner structures of the foot. Routine regular hoof care (trimming and shoeing) is strongly recommended for every horse to prevent them from developing cracks and lameness.

Hoof cracks can be caused by long, untrimmed, and/or unbalanced feet creating hoof wall flares and separation of the hoof wall from the white line. Some other causes are environmental factors such as an environment that shifts from wet to dry. A wet environment allows moisture, mud, dirt, and debris to migrate through the hoof wall separations. When the hoof environment dries, the debris becomes trapped inside the hoof capsule, allowing anaerobic (not requiring oxygen) bacteria to take over.

Poor hoof wall quality due to nutritional deficiencies can also play a role in hoof cracks. Therefore, besides routine regular hoof care, a balanced diet and hoof supplements can help your horse’s hoof quality. In my experience, certain hoof dressings applied over the coronary band (I use Contender by Kinetic) will stimulate a healthy hoof growth.
