Overview
If your horse’s heels smell bad and look greasy, it’s often a sign that the skin is staying damp, dirty or irritated. Greasy heel is a common owner concern, and there can be several possible reasons, from mud and wet weather to skin sensitivity or a secondary skin infection. You can usually start by checking the skin and the horse’s environment, then adjust routine care to keep the area cleaner and drier.
Things To Check
1. Check whether the problem is worse after turnout, muddy fields, washing, or sweating.
2. Look closely for redness, scabs, small crusts, swelling, heat, or broken skin around the heels and lower legs.
3. Smell the area and note whether there is a strong musty, sour or unpleasant odour, which can suggest the skin is staying very damp.
4. Check if the horse is stamping, itching, biting, or seeming uncomfortable when the legs are touched.
5. Feel whether the heels or lower legs are persistently wet, greasy or muddy rather than just dirty on the surface.
6. Think about whether rugs, boots, bandages or clipping may be trapping moisture or rubbing the area.
7. Check if other areas of skin are affected too, since more widespread irritation can point to a broader skin issue.
Common Causes
The most common cause is prolonged dampness, mud and dirt sitting on the skin, especially in wet fields or after washing. This can leave the heels looking greasy and smelling unpleasant.
Skin irritation from friction, sweat or grooming products can also make the area look oily or feel uncomfortable.
In some horses, greasy heel can be linked to a skin infection or inflammation. This is more likely if there are scabs, soreness, swelling or the problem keeps returning.
Less commonly, underlying skin sensitivity or another skin condition may be involved, especially if more than one area is affected.
What To Do
Keep the area as clean and dry as practical. If the legs are muddy, gently remove the dirt and dry them well rather than leaving moisture to sit on the skin.
Try to reduce repeated wetting where possible, and avoid leaving the lower legs damp after washing or exercise.
Check turnout and stable conditions too. Deep mud, damp bedding and dirty surfaces can all make the problem harder to settle.
Monitor the area for a few days so you can tell whether it is improving, staying the same or getting worse.
If the skin looks sore, very scabby, swollen or more uncomfortable, it’s sensible to get veterinary advice so the cause can be properly assessed.
When To Contact A Vet
Speak to your vet if the greasy, smelly heels are not improving with sensible cleaning and drying, if the skin is becoming more inflamed, or if your horse is painful, swollen, lame or very bothered by the area.
You should also contact your vet sooner if there is discharge, spreading scabs, marked heat, or the problem is affecting several areas of skin.
Products That May Help
If your horse’s heels are getting greasy or smelly after turnout, a routine that supports clean, dry legs can be helpful as part of day-to-day management.
