Overview
If scabs are leaking or smelling bad, it often means the area is staying too wet, the skin is very irritated, or there may be a secondary infection. It’s worth checking closely, but this doesn’t always mean anything severe. The main thing is to look for signs that the skin is worsening, not just drying out.
Things To Check
1. Check whether the area smells stronger after turnout, washing, or a muddy walk from the field. A wet environment can make scabs break down and smell more noticeable.
2. Look closely for heat, swelling, redness or soreness around the scabs. These changes can suggest the skin is more inflamed than it first appeared.
3. See whether the scabs are weeping clear fluid, yellowish discharge or thicker pus-like fluid. The type of leakage can help you judge how irritated the area seems.
4. Check if the horse is stamping, licking, rubbing or fussing with the leg. Ongoing irritation can make the skin break open and delay settling down.
5. Feel whether the lower leg seems puffy or if the horse is uncomfortable when you touch it. New swelling can mean the problem is spreading beyond the scabs themselves.
6. Look at the skin around the scabs for cracks, bald patches, crusting or fresh raw areas. Mud fever often affects more than one small spot.
7. Check for lameness or a shorter stride, even if it’s mild. If the horse is moving differently, the issue needs closer attention.
Common Causes
The most common cause is mud fever skin that has stayed damp and has started to soften, crack or ooze. That can produce a sour smell, especially if mud, sweat or dirty bedding is sitting on the area.
Sometimes the scabs are leaking because they have been disturbed, picked at or rubbed off too early, leaving raw skin underneath.
A bacterial skin infection can also build up in damaged skin and make the area smell unpleasant or discharge more than expected.
Less commonly, there may be more widespread skin inflammation, rain scald, or another skin problem alongside the mud fever.
What To Do
Keep the area as clean and dry as you reasonably can. Gently remove mud and loose debris, then dry the skin thoroughly after washing or turnout if the horse is still in a muddy patch.
Avoid scrubbing hard or picking scabs off, as that can make the skin more raw and delay healing. If the horse is turned out in wet ground, try to reduce time in the worst mud where possible.
Change any dirty, damp bedding and keep an eye on whether the smell or leakage improves over the next day or two. Taking a photo can help you compare changes over time.
If the leg becomes more swollen, more painful, or the horse starts to look unwell, get veterinary advice rather than trying to manage it yourself.
When To Contact A Vet
Contact your vet if the area is getting worse, the smell is strong and persistent, there is thick discharge, the skin is very painful, or the horse is lame or noticeably swollen. These signs can mean the skin needs a proper examination and a different level of treatment.
Products That May Help
Keeping muddy legs clean and dry is often a big part of managing mud fever day to day. The right routine products may help support that care and make washing, drying and general hygiene easier.
