Overview
Scabs on the back of the heels are often linked to greasy heel, especially if the skin is staying damp, muddy or rubbed. They can also be caused by irritation, minor skin damage or other skin problems, 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 on one horse, one leg, or both heels.
2. Check for heat, swelling, redness, soreness or broken skin around the heels and pasterns.
3. See whether the scabs are linked to wet turnout, muddy fields, washing, sweating or clipped hair.
4. Notice if your horse is stamping, lifting a foot, resenting touch or seeming uncomfortable when the area is handled.
5. Check for hair loss, thickened skin, crusting, discharge or a greasy look to the feathers or heel area.
6. Think about any recent changes in bedding, turnout, grooming, boots or brushing that could be rubbing the skin.
7. Watch whether the scabs keep returning after they’ve been cleaned or whether the area is slowly worsening.
Common Causes
The most common cause is greasy heel, which often develops in damp or muddy conditions and can leave the skin sore, crusty and scabby.
Skin irritation from mud, sweat, washing or friction can also cause scabbing, especially if the heels are frequently wet and then left to dry unevenly.
Less commonly, a bacterial or fungal skin issue, mites, or another skin condition may be involved, particularly if the problem spreads, becomes painful or doesn’t settle with sensible routine care.
What To Do
Keep the area as clean and dry as you reasonably can. Remove mud gently, dry the heels well and avoid over-washing, which can sometimes irritate the skin further.
Check turnout, bedding and grooming routines for anything that may be keeping the skin wet or rubbing the back of the legs. If the horse is feathered, check that mud is not sitting against the skin for long periods.
Try to avoid picking scabs off, as that can make the skin more sore and delay healing. Instead, monitor whether the area is improving, staying the same or becoming more inflamed.
When To Contact A Vet
Speak to your vet if the skin is very sore, swollen or oozing, if the scabs are spreading, or if your horse seems noticeably uncomfortable. It’s also sensible to get advice if the problem keeps coming back or doesn’t improve with good hygiene and environmental management.
