Overview
Greasy, scabby skin behind the heels is often a sign that the skin there is being irritated by moisture, mud, friction or a skin infection such as pastern dermatitis. It can also be linked to sensitive skin or repeated washing. There are several possible causes, so it’s worth checking the area carefully rather than assuming it’s just dirt.
Things To Check
1. Look at whether the scabs are only behind the heels or also higher up the pasterns and lower legs.
2. Check if the skin feels warm, swollen, sore or looks red underneath the scabs.
3. Notice whether the problem gets worse after muddy turnout, wet bedding, or washing the legs.
4. See if there is any discharge, cracking, hair loss or a greasy, sticky coating on the skin.
5. Check whether your horse is stamping, scratching, resisting leg handling or seems uncomfortable when cleaned.
6. Think about whether new turnout conditions, rugs, boots, grooming products or detergents could be irritating the skin.
7. Compare both legs, because similar changes on more than one leg can point towards an environmental or skin-related issue.
Common Causes
The most common cause is skin irritation from mud, moisture and repeated wetting, especially around the heels where dirt tends to sit. This can leave the skin greasy, sore and scabby.
Another common cause is pastern dermatitis, which is a broad term for inflammation of the skin in this area. It may be triggered by wet conditions, friction, minor skin damage or underlying sensitivity.
In some horses, clipping, washing too often or harsh grooming products can upset the skin barrier and make the area more likely to become scabby.
Less commonly, bacteria, fungi or mites may be involved, particularly if the area is spreading, very itchy or not improving with good basic care.
What To Do
Keep the area as clean and dry as you reasonably can. If you need to wash the legs, do it gently and dry them well afterwards, especially in the heel area.
Reduce repeated mud exposure where possible. Dry bedding, cleaner turnout areas and avoiding long periods in wet, dirty conditions may help support the skin while it settles.
Don’t pick scabs forcefully, as that can make the skin more sore. If the area is only lightly dirty, gentle cleaning is usually kinder than scrubbing.
Watch for any pattern in when it flares up. A simple note of turnout, weather, washing and grooming can make it easier to spot what’s making it worse.
If the skin keeps coming back, spreads, or your horse seems uncomfortable, it’s sensible to get veterinary advice so the cause can be properly assessed.
Products That May Help
If your horse is dealing with muddy turnout, damp legs or repeat heel scurf, a routine focused on hoof and leg hygiene may be useful alongside good stable and turnout management.
