Overview
Scabs on the lower legs in wet weather are often linked to mud fever, which is a common skin irritation that can appear when legs stay damp or muddy for too long. Other things can look similar, so it’s worth checking the skin closely rather than assuming it’s one simple cause.
Most cases are noticed on the pasterns or heels after turnout in wet, muddy ground, but scabs can also happen with rubbing, minor skin damage or other skin problems.
Things To Check
1. Check whether the scabs appear after turnout in wet fields, muddy gateways or long spells of rain.
2. Look closely for redness, swelling, heat, broken skin, discharge or tenderness around the lower leg.
3. Note whether the horse seems uncomfortable when the area is touched or when the legs are washed and dried.
4. See if the problem is on one leg or several, and whether it’s in the same place each time.
5. Check for signs of rubbing from boots, bandages, grooming tools or turnout equipment.
6. Look at the surrounding skin for crusting, hair loss or areas that seem sore or sticky.
7. Consider whether the horse has been in very wet bedding, stayed wet after exercise, or been turned out without a chance to dry properly.
Common Causes
The most common cause is mud fever, sometimes called pastern dermatitis, which is often linked with wet, muddy conditions and skin that stays soft or irritated.
Repeated wetting and drying can make the skin barrier more fragile, which may lead to scabs and soreness.
Less commonly, the scabs may be caused by rubbing, insect irritation, a minor wound that’s crusting over, or another skin condition that needs a closer look.
What To Do
Keep the area as clean and dry as you realistically can, especially after turnout.
If the legs are muddy, gently remove the worst of the dirt and dry the skin carefully rather than scrubbing hard.
Reduce repeated wetting where possible, and keep an eye on whether the problem settles or keeps coming back.
If the horse is living out, check whether improving shelter, turnout timing or stable routine might help reduce how long the lower legs stay damp.
Try not to pick scabs off, as that can make the skin more sore and delay healing.
If the problem keeps returning, spreads, or the horse seems sore, it’s worth getting a vet’s opinion so the skin can be assessed properly.
