Overview
Thick scabs and hair loss around the heels are often seen with greasy heel, but they can also happen with mud, skin irritation or other mild skin problems. It’s worth checking the area closely, because the best next step depends on whether the skin is just dirty and crusty or actually sore, swollen or weeping.
You may be able to manage mild cases with careful cleaning, keeping the area dry and watching for changes. If the skin looks more inflamed, spreads, or your horse seems uncomfortable, it’s sensible to speak to your vet.
Things To Check
1. Check whether the scabs are only around the heels or whether they extend up the pastern and lower leg.
2. Look for redness, heat, swelling, soreness, broken skin or any sticky discharge under the scabs.
3. Notice if your horse reacts when the area is touched, picked at or cleaned.
4. Think about whether the problem is worse after wet turnout, muddy fields or regular washing.
5. Check whether both hind legs are affected or whether it is limited to one leg.
6. Look at the skin elsewhere for similar crusts, dandruff, rubbing or patchy hair loss.
7. Notice if the horse is stamping, licking, itching or showing any change in movement that could suggest discomfort.
Common Causes
Greasy heel is one of the most common reasons, especially when the heels stay damp, dirty or muddy for long periods. It can cause thick crusts, scabbing, hair loss and sometimes soreness.
Moisture and mud irritation can also make the skin around the heels break down, particularly in wet weather or after repeated washing.
Less often, similar changes can be linked to skin infection, mites, allergic irritation or rubbing from boots, bandages or tack that sits too low.
In some horses, the skin simply becomes more sensitive when the coat is long, the area is difficult to dry properly, or mud keeps collecting around the lower legs.
What To Do
Keep the area as clean and dry as you can without overdoing washing. Gentle routine cleansing followed by thorough drying is often more helpful than scrubbing hard.
Try to reduce prolonged mud and moisture on the lower legs where possible. If turnout conditions are very wet, check the legs daily and dry them carefully after exercise or washing.
Do not pick scabs aggressively, because that can make the skin more sore and slow down healing. If crusts are loose, they may lift away with careful washing, but stop if the area becomes painful.
Watch the area for a few days and note whether it is improving, staying the same or spreading. If it is getting worse or your horse seems uncomfortable, get veterinary advice.
When To Contact A Vet
Contact your vet if the skin is very sore, swollen, hot or oozing, if the problem is spreading, or if your horse is lame or clearly uncomfortable. It’s also sensible to get advice if the scabs keep returning, the hair loss is worsening, or home care isn’t making any difference.
