Why is my horse suddenly lame with a hoof crack?

Overview
If your horse has suddenly gone lame and you can see a hoof crack, the crack may be part of the problem, but it’s not the only possible cause. It could be a surface crack, a deeper split, a bruised sole, a loose shoe, a stone, or an issue higher up in the leg that only looks like hoof lameness at first.
Start by looking closely at the hoof and the way your horse is standing and moving. A sudden change in lameness, especially if the foot is hot, painful to touch, or there’s swelling higher up, deserves prompt attention.
Things To Check
1. Watch whether the lameness is mild, obvious, or getting worse when your horse turns or walks on a hard surface.
2. Check the crack itself for depth, width, movement, or any signs it has reached sensitive parts of the hoof.
3. Feel for heat in the hoof and compare it with the other feet if you can do so safely.
4. Look for pulse changes in the foot, since a stronger-than-usual digital pulse can suggest the foot is irritated or inflamed.
5. Check for a loose, twisted, or missing shoe, trapped stones, or anything wedged into the sole or frog.
6. Look for swelling, cuts, or tenderness higher up the limb, not just at the hoof.
7. Notice whether the horse is reluctant to move, turning a foot, or resting one leg more than usual.
Common Causes
The most common reason is that the crack has become painful because the hoof wall is stressed, split deeper than it first looked, or is pulling on sensitive structures. That can happen after hard ground, overgrown hooves, poor balance, or a shoe issue.
Other common causes include a bruise, a stone bruise, thrush-related soreness, a loose shoe, or a nail problem if the horse is shod. Sometimes the crack is just the visible part of a wider hoof problem rather than the main cause.
Less commonly, lameness may be coming from an abscess, laminitis, or an injury higher up the limb that makes the horse alter how it stands and walks. You can’t reliably tell the difference without a proper examination if the lameness is sudden or significant.
What To Do
Keep your horse on a calm, clean surface and limit unnecessary movement until you know more. If the horse is comfortable enough to do so, check the hoof carefully for trapped debris, a loose shoe, or obvious damage, but don’t dig around the crack.
Take note of when the lameness started, whether it changes on different ground, and whether the foot feels hot or pulsing. This information can help your farrier or vet judge how urgent the problem may be.
If the hoof is muddy or dirty, gentle cleaning and keeping the foot dry may help you monitor it more clearly. Make sure turnout and stable conditions are as sensible as possible, with footing that doesn’t add extra strain.
Arrange a farrier visit if the crack looks unstable, the shoe is loose, or the hoof balance seems to have changed. If the lameness is sudden, marked, or the horse is very painful, vet input is appropriate as well.
When To Contact A Vet
Contact your vet promptly if the lameness is severe, your horse won’t bear weight, the hoof is very hot or pulsing, there is major swelling, or the horse seems increasingly distressed. Sudden lameness with a hoof crack can sometimes involve an abscess, deeper hoof pain, or another problem that needs treatment advice.
If the horse has a fever, is very dull, or the problem is not improving quickly, it’s sensible to get a veterinary assessment rather than waiting it out.
Products That May Help
Keeping the hoof, legs and turnout area clean and easier to inspect can be helpful when you’re monitoring cracks, mud and hoof-related changes at home.
