Overview
If your horse has mild mud fever, you can often start with careful home management, but call the vet if it’s not improving, seems painful, or the skin is getting worse. Mud fever is usually linked to wet, dirty conditions and skin damage, but similar-looking signs can have other causes too.
Things To Check
1. Check whether the skin is just a bit scurfy or whether there are scabs, cracks, discharge, swelling or heat.
2. Look at how sore your horse seems when you touch the area, pick up the leg, or wash it.
3. See if the problem is limited to the heels and pasterns or if it’s spreading up the leg.
4. Think about whether it appears after turnout in mud, after washing, or when the legs stay damp for long periods.
5. Check for lameness, shortened stride, or any reluctance to move normally.
6. Note whether one leg is affected or several legs are involved.
7. Watch for flies, rubbing, or other skin irritation that could be making the area harder to heal.
Common Causes
The most common cause is skin irritation from wet, muddy, or dirty conditions, especially when the legs stay damp for long periods.
It can also follow minor skin damage, clipping, washing, or rubbing from boots, bandages, or coarse bedding.
Sometimes similar signs can be linked to bacterial or fungal skin infection, mites, or other skin problems that need a closer look.
What To Do
Keep the area as clean and dry as you can without over-washing. If the skin is dirty, use gentle cleaning and dry it thoroughly afterwards.
Try to reduce time spent in deep mud where possible, and keep bedding, turnout areas and stable corners as clean as practical.
Monitor the skin daily so you can spot changes early, especially if the scabs are spreading or the leg is becoming more uncomfortable.
If your horse is sensitive, painful, or the area keeps returning, ask your vet for advice rather than trying to manage it alone.
When To Contact A Vet
Contact your vet if the area is hot, swollen, painful, or causing lameness, if the skin is oozing or the scabs are spreading, or if it hasn’t improved after a few days of sensible care. You should also get advice sooner if your horse seems unwell, the problem is affecting several legs, or you’re not sure it’s mud fever at all.
