Why does my horse have a crack in its hoof wall?

Overview
A crack in the hoof wall is fairly common and can happen for a few different reasons. It may be a surface crack, a line caused by dryness or wear, or a sign the hoof is under uneven pressure. It’s worth checking carefully, but many cracks are manageable once you know what’s behind them.
Things To Check
1. Check where the crack starts and ends. A small chip near the bottom is usually different from a crack that runs upwards from the ground surface.
2. Look for heat, swelling, lameness or a shorter stride, as these can suggest the hoof is sore rather than just dry or worn.
3. See whether the crack is open, bleeding, crumbly or collecting dirt, which can give a clue about how stable it is.
4. Note whether the hoof is very dry, brittle or exposed to repeated wet and dry conditions, since these can affect the hoof wall.
5. Check if the horse has had a recent trim or shoeing change, because balance or uneven loading can sometimes show up as cracking.
6. Compare all four feet if you can. A single hoof with a problem may point to a local issue, while several cracked hooves can suggest a general hoof condition or management factor.
7. Watch whether the crack seems to be getting longer, deeper or more painful over a few days.
Common Causes
Dry, brittle hooves are one of the most common reasons for hoof wall cracks, especially after hard ground or changes in weather. Repeated wet and dry conditions can also weaken the hoof wall and make it split more easily.
Poor hoof balance, long toes, uneven wear or an overdue trim can place extra strain on one part of the hoof. A small knock or knock-on damage from a stone, shoe or fence can also start a crack.
Less commonly, a crack may be linked to an abscess track, a deeper hoof wall injury, or an ongoing hoof growth problem. These are more likely if the horse is lame, the hoof is hot, or the crack keeps worsening.
What To Do
Keep the hoof clean and pick it out regularly so dirt and grit don’t pack into the crack. If the hoof is very dry, avoid over-washing and try to keep the horse on consistent footing where possible.
Make a note of the crack’s position and size, then monitor it over time. A photo every few days can help you see if it’s stable or changing.
If your horse is shod, speak to your farrier about whether the hoof needs balancing, a more frequent trim, or support while the hoof grows out. If the horse is barefoot, regular trimming and sensible turnout conditions can help reduce strain.
It’s also worth reviewing the horse’s daily environment. Very muddy ground, hard standing or repeated damp and dry conditions can all make hoof care more difficult.
When To Contact A Vet
Contact your vet if the horse is lame, the hoof is hot or swollen, the crack is bleeding or deep, or the crack appears to be moving upwards towards the coronary band. You should also get advice if the hoof smells foul, there’s discharge, or the horse seems increasingly uncomfortable.
Your vet may work alongside your farrier if the crack seems to involve deeper hoof structures or if there’s an underlying hoof problem that needs a closer look.
Products That May Help
Keeping hooves, legs and muddy turnout areas clean and manageable can make day-to-day hoof care easier, especially when cracks seem linked to wet ground or messy conditions.
