Overview
If your horse's legs are red under the scabs, it's often a sign that the skin is irritated and the area is still inflamed. With mud fever, that can happen for several reasons, including wet conditions, friction, scratching, or the skin not settling properly as the scabs lift.
It doesn't automatically mean something serious, but it is worth checking the skin carefully so you can decide whether simple management changes are enough or whether your vet should take a look.
Things To Check
1. Check whether the redness is only under the scabs or whether it spreads beyond them onto nearby skin.
2. Look for heat, swelling, discharge, a bad smell, or new scabs forming quickly.
3. See if your horse is sore when you touch the area, picks up the leg, or reacts more than usual during cleaning.
4. Check whether the problem is worse after turnout, muddy fields, stable time, clipping, or leg washing.
5. Look at both legs. Mud fever often affects the lower legs, but it can be uneven, with one leg looking worse than the others.
6. Check for cracks, broken skin, crusting, weeping, or hair loss around the red areas.
7. Consider whether anything has changed recently, such as new bedding, wetter ground, bandaging, or a different grooming routine.
Common Causes
The most common cause is ongoing skin irritation from mud fever itself, especially if the skin is wet, muddy or repeatedly disturbed as scabs loosen.
Redness can also happen if the skin has been rubbed by mud, brushing, boots, bandages or washing that is a bit too frequent or too harsh for the area.
Sometimes the skin is reacting to a secondary infection or to tiny cracks in the surface, which can make the area look red and sore underneath the scabs.
Less commonly, another skin problem may be involved, so it is sensible to keep watching how the area changes rather than assuming it is all the same thing.
What To Do
Keep the area clean, but be gentle. Use careful washing only if it helps remove dirt, then dry the legs well afterwards.
Try to keep muddy turnout to a minimum where you can, and make sure the horse has access to a drier area if possible.
Avoid picking scabs off, because that can leave the skin raw and make the redness worse.
Watch the area over the next few days so you can see whether it is calming down, staying the same, or getting more inflamed.
If the legs are getting wetter, soreder or more swollen, or if your horse seems uncomfortable, it is sensible to get veterinary advice.
When To Contact A Vet
Contact your vet if the redness is spreading, the skin is hot or swollen, there is discharge, your horse is clearly painful, or the legs are not improving with sensible home care. A vet should also see your horse if you notice lameness, marked swelling, or the problem keeps coming back.
Products That May Help
If your horse is dealing with muddy turnout, damp legs or scabby lower legs, a routine focused on gentle cleaning and drying may be useful alongside your usual care.
