Mud fever (also called pastern dermatitis or “greasy heel”) is a common skin condition in horses, usually seen on the lower legs, caused by a mix of factors: constant wet/muddy conditions, bacterial infection (often Dermatophilus congolensis), fungi, mites, or even photosensitivity.
Here’s a clear approach to help manage it:
Immediate Care
-
Bring the horse out of wet/muddy conditions as much as possible (use dry turnout or stable).
-
Clean gently:
-
Use lukewarm water or a mild diluted antiseptic wash.
-
Avoid scrubbing hard — it can make the skin raw.
-
-
Dry thoroughly: Pat dry with a clean towel. Keeping the area dry is essential. Use a dry clean towel per leg to avoid spreading infection and change them each day.
Topical Treatments
-
Apply a protective barrier cream once the skin is clean and dry. Ideally ones containing active ingredients to treat the infection.
-
Some owners use natural soothers like neem oil, or manuka or lavender(for their antibacterial/soothing properties).
- Avoid the use of products containing minerals oil which can prevent the skin from breathing and healing properly.
Management & Prevention
-
Clip excess feathers if the horse has heavy leg hair (so skin can stay dry).
-
Change bandages/wraps daily if covering the legs (but often leaving uncovered is better once dry).
-
Avoid harsh washing every day – too much moisture can slow healing.
-
Check for mites (especially in feathered breeds), as they can worsen mud fever.
When to Call the Vet
-
If the skin is hot, swollen, or painful.
-
If the infection is spreading up the leg.
-
If the horse becomes lame.
-
If scabs are severe and not improving after a few days.
