Overview
A crack at the heel of the hoof can mean the hoof wall is under strain, has had a change in moisture, or the foot is wearing unevenly. In many cases it’s a management issue rather than an emergency, but it’s worth checking carefully because heel cracks can sometimes be linked to discomfort, poor balance or ongoing hoof stress.
Things To Check
1. Check whether the crack is shallow or if it seems to travel deeper into the hoof wall.
2. Look for heat, sensitivity, swelling or a change in how your horse is standing or moving.
3. Check the hoof for soft, crumbly, dry or flaring edges, especially if the footing has changed recently.
4. Notice whether the crack looks worse after wet turnout, muddy conditions or a recent trim or shoeing.
5. Check the frog, heel bulbs and lower foot for soreness, smell, discharge or signs of thrush-type issues.
6. Look at all four feet to see if the problem is only in one hoof or part of a wider hoof balance issue.
7. Ask yourself whether the horse has had any recent increase in work, harder ground or a change in exercise pattern.
Common Causes
The most common causes are moisture changes, wear and tear, and hoof balance issues after trimming or shoeing. A heel crack can also develop when the hoof wall is dry and brittle, when the foot is under uneven load, or when the horse is working on hard or abrasive ground.
Less commonly, a crack may be associated with bruising, thrush-related heel weakness, or a hoof problem that needs closer assessment. The crack itself doesn’t tell you the whole story, so the surrounding hoof and how the horse is moving matter too.
What To Do
Keep the hoof clean and check it regularly so you can spot changes early. Try to keep turnout and stable conditions as consistent as you can, since repeated wet and dry swings can make hoof walls more fragile.
Make sure the hoof is picked out daily and look for any sign that the crack is spreading. If your horse is shod or regularly trimmed, let your farrier know so they can assess whether the heel needs support or whether the trim balance needs adjusting.
Keep a simple record of the crack with a photo every few days. That makes it easier to tell whether it’s stable, improving or getting worse.
When To Contact A Vet
Contact your vet if the crack is deep, bleeding, spreading, or if your horse is lame, uncomfortable, or reluctant to load the foot. It’s also sensible to get advice if the heel looks swollen, hot or painful, or if the crack keeps returning despite regular farrier care.
If the horse has a sudden change in movement or a marked increase in hoof pain, don’t wait to see whether it settles.
