Overview
Hard scabs that won’t come off are often seen with mud fever, but they can also happen with other skin irritation or infection on the lower legs. It’s usually best not to pick at them, because that can make the skin sore or open.
Things To Check
1. Check whether the scabs are on the lower legs, especially around the heels or pasterns, where mud and moisture often sit.
2. Look for redness, heat, swelling, cracking, wet skin, or any discharge around the scabs.
3. Notice if your horse is sore when the area is touched or if they’re stamping, leaning, or reacting more than usual.
4. Think about recent turnout in muddy ground, wet bedding, or standing in damp conditions.
5. Check whether the scabs are spreading, multiplying, or reappearing after you’ve cleaned the area.
6. See if the skin feels thickened, flaky, crusty, or broken underneath where the scabs sit.
7. Make sure there isn’t a strong smell, pus, or extra heat, which can suggest the skin needs closer attention.
Common Causes
The most common reason is mud fever, where the skin on the lower legs becomes irritated and forms crusty scabs, especially in wet or muddy conditions.
Other common causes include minor skin infection, general dermatitis, or friction from wet mud, bedding, or leg grooming. In some horses, clipped skin or sensitive skin can make scabs more noticeable and harder to shift.
Less commonly, a deeper infection or a different skin problem may be involved, especially if the area is painful, very swollen, or not improving.
What To Do
Don’t force the scabs off. That can tear the skin and make the problem worse. Instead, keep the area clean and dry, and only handle it gently.
If the skin is muddy, soften the dirt first and clean carefully rather than scrubbing. Dry the leg well afterwards, because lingering dampness can keep the irritation going.
It also helps to reduce exposure to wet, muddy ground where possible and to keep an eye on whether the scabs are changing over a few days. If the area worsens, becomes painful, or starts to ooze, a vet check is sensible.
Products That May Help
A routine-focused collection for hoof and lower-leg care may be useful when you’re managing muddy turnout, keeping legs clean, and supporting everyday hygiene around the lower limb.
