Overview
If your horse has mud fever on both hind legs, check the skin, the mud exposure and whether anything in the routine has changed. Bilateral mud fever is often linked to wet, dirty conditions or irritation from washing and moisture, but there can be several possible causes.
Things To Check
1. Check when the problem started and whether it seems worse after turnout, washing, exercise or box rest.
2. Look closely for redness, scabs, broken skin, swelling, heat or any discharge on both hind legs.
3. Check whether the legs stay damp for long periods after turnout, hosing or washing.
4. Look at the field or gateway area for mud, standing water, wet bedding or dirty stable floors.
5. Check whether your horse is stamping, sore when the legs are touched, or a bit reluctant to pick up a hind leg.
6. Consider whether clipping, feathering, grooming products or recent leg care changes might have irritated the skin.
7. Check the other legs and the lower belly or heels for any similar skin changes.
Common Causes
The most common cause is prolonged exposure to wet, muddy or dirty conditions, especially if the skin stays damp. Repeated washing or leaving legs wet after cleaning can also irritate the skin and make it easier for mud fever to develop.
Sometimes the issue is made worse by friction from feather, rug edges or tack, or by sensitive skin that reacts more strongly to moisture and dirt. Less commonly, another skin problem may be involved, so it’s worth keeping an open mind if it doesn’t look typical.
What To Do
Start by keeping the legs as clean and dry as you reasonably can. If they’re muddy, gently remove the worst of the dirt without rubbing hard, then dry the area carefully. Try to avoid soaking the legs for long periods unless your vet has told you otherwise.
Improve the turnout and stable routine where possible. That might mean reducing time in the wettest areas, picking clean bedding more often, and keeping an eye on whether the legs are getting wet again straight after cleaning.
Watch for changes over the next few days. If the skin looks calmer, keep the routine steady. If it’s getting more sore, spreading, or your horse seems uncomfortable, that’s a sign to get advice.
When To Contact A Vet
Speak to your vet if the skin is very painful, there is marked swelling or heat, lameness develops, discharge appears, or the problem is not improving with sensible cleaning and drying. They can help check whether this is straightforward mud fever or something else that needs different treatment.
Products That May Help
If mud fever is linked to wet turnout, muddy fields or routine leg washing, a sensible hygiene routine may help support day-to-day management and keep legs easier to check.
