Overview
If your horse is lame with mud fever, it’s worth taking it seriously and checking the leg and hoof carefully. Mud fever can make the skin sore enough to affect how they move, but lameness can also mean there’s something else going on, such as a deeper infection, bruising, an abscess or a separate leg or hoof problem.
Start by looking closely at the skin, hoof and the rest of the leg, then keep the area clean and dry while you watch for change. If the lameness is clear, getting worse, or your horse seems very painful, vet advice is appropriate.
Things To Check
1. See whether the lameness is mild or whether your horse is reluctant to bear weight, turn, or walk forward.
2. Look closely for scabs, raw skin, swelling, heat, discharge, crusting, hair loss or cracked skin around the heels and lower legs.
3. Check the hoof for stones, loose shoes, thrush smell, a strong digital pulse or any sign that the foot itself is painful.
4. Feel both lower legs for heat, puffiness or soreness compared with the other side.
5. Notice whether the problem appeared after wet turnout, muddy fields, box rest, grooming, exercise or picking out the feet.
6. Check whether your horse is otherwise bright, eating and happy to move, or whether they seem dull, miserable or off their food.
7. Think about whether the mud fever has been present for a while, keeps coming back, or has suddenly become more painful.
Common Causes
The most common reason is sore, inflamed skin from mud fever itself, especially if the lower legs have stayed wet, dirty or irritated for a while.
Sometimes the lameness comes from secondary infection, deeper skin soreness, swelling or enough pain that the horse starts to alter how they place the leg.
It can also be something separate from mud fever, such as a hoof abscess, bruising, a strain, a stone in the foot or another cause of lameness that just happens to be noticed at the same time.
What To Do
Keep your horse as clean and dry as you reasonably can and limit time in deep mud where possible. If the skin is dirty, gently remove surface mud with care and avoid aggressive scrubbing, which can make sore skin worse.
Check the foot and lower leg every day for changes in heat, swelling, discharge or worsening pain. If the skin is broken, swollen, very sore or the lameness is not settling, don’t keep trying to manage it as simple mud fever alone.
Give your horse a clean, dry place to stand if you can, and keep the routine calm and simple. If turnout is unavoidable, reducing wet exposure and keeping the legs as dry as possible may help support day-to-day management.
When To Contact A Vet
Contact your vet if the lameness is obvious, worsening, or your horse is unwilling to bear weight, has marked heat or swelling, or seems very painful. You should also call if there is discharge, spreading skin damage, a fever, or if the foot seems painful as well as the skin.
It’s also sensible to get veterinary advice if the problem keeps returning, isn’t improving with sensible management, or you’re not confident the lameness is only due to mud fever.
Products That May Help
If your horse is dealing with muddy turnout, sore lower legs or recurring heel and skin care concerns, a simple washing and daily care routine can be easier to manage with the right kit to hand.
