Overview
Crusty, sore legs in horses are often linked to mud fever, especially after wet turnout or if the skin has been kept damp and dirty. It can also be caused by other skin irritation, so it’s worth checking the area closely rather than assuming it’s just mud.
The good news is that many mild cases can be managed with sensible cleaning, drying and better day-to-day hygiene. If the skin is very painful, swollen, oozing, or your horse is lame, a vet should check it.
Things To Check
1. Check whether the problem is worse after muddy turnout, wet bedding, grooming, clipping or exercise.
2. Look for scabs, crusting, redness, broken skin, discharge, swelling or heat on the lower legs.
3. See whether one leg or several legs are affected, and whether the sore areas are on the heels, pasterns or up the cannon bone.
4. Notice if your horse reacts when you touch, clean or dry the area, as that can show how sore it is.
5. Check for mud, wet hair, feathering, cuts or small skin cracks that may be trapping dirt and moisture.
6. Watch for lameness, stiffness, a change in way of going, or reluctance to move.
7. Consider whether flies, rubbing, or repeated washing could be irritating the skin as well.
Common Causes
Mud fever is a common cause, especially when the skin stays wet, dirty or muddy for long periods. It often affects the lower legs first and can leave crusts, soreness and scabs.
Other common possibilities include simple skin irritation from mud, repeated washing, friction, minor cuts, or sensitive skin that has become inflamed.
Less commonly, the problem may involve infection deeper in the skin, pastern dermatitis from several contributing causes, or another skin condition that needs targeted treatment.
What To Do
Start by keeping the legs as clean and dry as you can. Gently remove mud with lukewarm water if needed, then dry the area carefully. Avoid harsh scrubbing, because that can make sore skin worse.
Reduce exposure to wet mud if you can. That might mean changing turnout, improving shelter, picking cleaner grazing routes, or avoiding turnout in the worst ground when practical.
Check bedding, stable hygiene and grooming routines too. Damp, dirty conditions can keep the skin irritated, so a cleaner, drier environment often helps support recovery.
Keep an eye on whether the crusting is spreading, whether the skin is getting more painful, and whether your horse is becoming less willing to have the legs handled. If it’s not improving, or it’s getting worse, get veterinary advice.
When To Contact A Vet
Contact your vet if the legs are very painful, swollen, hot or oozing, if your horse is lame, or if the crusting is spreading quickly. You should also get advice if there’s no improvement after a few days of sensible cleaning and drying, or if the same problem keeps coming back.
