Why is my horse’s hoof cracked?

Overview
A cracked hoof is fairly common and can happen for several reasons. It may be due to dry or wet-dry changes in the environment, wear, a hoof that needs trimming, or a small imbalance in how the foot is loading. Some cracks are only cosmetic, while others need closer attention.
The important thing is to check how deep the crack is, whether it’s changing, and whether your horse is sore or moving differently.
Things To Check
1. Look at where the crack starts and how far it runs. A short surface crack is usually less concerning than one that reaches higher up the hoof wall or seems to travel into sensitive areas.
2. Check whether your horse is lame, short-striding, footsore or reluctant to turn on that foot.
3. Feel for heat in the hoof and check for a stronger-than-usual digital pulse compared with the other feet.
4. Inspect the hoof for chips, loose horn, mud packing, a foul smell, discharge or any sign of bruising.
5. Think about recent changes such as very dry ground, prolonged wet conditions, new turnout, harder exercise or a delayed trim.
6. Compare the hoof with the others. A one-sided crack or a foot that looks noticeably different can point to uneven loading or balance issues.
7. Check the shoe if your horse is shod. A loose shoe, shifted nail or damaged shoe can make a crack worse.
Common Causes
Minor surface cracking is often linked to dry hooves, frequent changes between wet and dry conditions, or normal wear and tear.
Hooves that are a bit long, uneven, or overdue for trimming can also crack more easily because the wall is under extra strain.
Sometimes a crack develops after a knock, a stone bruise, or repeated impact on hard ground. In shod horses, shoe fit or movement of the shoe may play a part.
Less commonly, deeper cracks can be associated with more complex hoof balance issues or another problem lower in the foot that needs professional assessment.
What To Do
Keep the hoof clean and pick it out daily so you can see whether the crack is changing.
Make a note of its size, position and appearance. A photo every few days can help you spot progress or worsening.
Try to keep turnout and standing areas as consistent as you can, especially if the ground is very wet or very dry. Sudden changes in moisture can make some cracks worse.
Stick to a regular farrier routine, because balanced trimming is often one of the most useful parts of managing a cracked hoof.
If the hoof is chipped or rough at the edge, don’t try to dig into the crack or cut the wall yourself. It’s usually better to leave correction to a qualified farrier.
If the crack is small and your horse is comfortable, monitor it closely and keep an eye on any change in shape, depth or soundness.
When To Contact A Vet
Contact your vet if the crack is deep, bleeding, spreading, associated with lameness, heat, swelling or a strong pulse, or if the hoof looks unstable. A vet should also be involved if your horse seems significantly sore or the crack isn’t improving with routine farrier care.
Products That May Help
Keeping on top of hoof and yard hygiene may help support a steadier hoof care routine, especially if cracks seem worse in wet or muddy conditions.
