Overview
Scabby, flaky lower legs in winter are often linked to mud fever, which is a general term owners use for skin irritation on the lower limb. Wet ground, muddy turnout and damaged skin can all play a part, but there may be other causes too, so it’s worth checking the pattern and how your horse seems otherwise.
Things To Check
1. Look at when the scabs appear, for example after turnout, in wet weather, or after washing.
2. Check whether the skin is just flaky or whether there are scabs, redness, soreness, cracks, heat or swelling.
3. See if the problem is on one leg, both front legs, both hind legs or all four, as that can help you spot a pattern.
4. Feel whether the lower legs seem puffy, tender or warmer than usual.
5. Check the field, gateway and shelter areas for mud, standing water or very wet bedding.
6. Think about whether the legs have been washed recently, especially if they were left damp afterwards.
7. Look for signs your horse is uncomfortable, such as stamping, fussing when handled or avoiding having the legs touched.
Common Causes
Wet, muddy conditions are the most common reason lower legs become scabby and flaky in winter. Constant moisture can soften the skin and make it easier for irritation to develop.
Minor skin damage from mud, grit, repeated washing or rubbing can also leave the skin dry, scurfy and more likely to scab.
Sometimes the skin is reacting to something in the environment, such as wet bedding, dirty stable areas or persistent mud around fences and gateways.
Less commonly, a bacterial skin infection or another skin condition may be involved, especially if the area is painful, swollen or getting worse rather than settling.
What To Do
Keep the area as dry and clean as you reasonably can without over-washing. If you do wash the legs, dry them carefully afterwards.
Reduce time standing in deep mud if you can, and try to keep gateway and feeding areas as dry as possible.
Check the skin daily so you can spot changes early, especially if scabs are spreading or the skin looks more sore.
Avoid picking off scabs forcefully, as that can make the skin more irritated.
If the legs are becoming increasingly sore, swollen or weepy, or your horse seems unwell, it’s sensible to get veterinary advice.
