Overview
Greasy heel is usually not an emergency, but it can become more urgent if the skin is very sore, swelling is spreading, there is heat, pus, or your horse seems unwell. In many cases it starts as a skin irritation, but there may be several possible causes, including mud, wet conditions, friction, or an underlying skin problem.
If the area is only mildly scabby or dirty, you can often start with careful cleaning and close monitoring. If it looks angry, painful, or is getting worse quickly, it’s sensible to get veterinary advice.
Things To Check
1. Check whether the skin is just scabby, or whether there is swelling, heat, cracking, oozing, or obvious pain.
2. Look at how far the changes extend. Greasy heel that is spreading up the leg needs more attention than a small, local patch.
3. Notice whether your horse is lame, pottery, or reluctant to pick up the foot or let you touch the leg.
4. See if the problem is linked to wet turnout, muddy ground, heavy feathering, sweating, or washing the legs too often.
5. Check for broken skin, crusts, discharge, a bad smell, or signs the area has become infected.
6. Think about whether the horse has had similar flare-ups before, which can point to a recurring management issue.
7. Watch for general signs of illness such as dullness, reduced appetite, or a raised temperature.
Common Causes
The most common cause is skin irritation from prolonged damp, mud, or dirty bedding, especially around the heels and pasterns. Friction from feathering, clipped skin, or repeated washing can also make the area more vulnerable.
Sometimes greasy heel is linked to bacterial or fungal skin infection, especially if the skin is broken or stays wet for long periods. Less commonly, an allergic or immune-related skin problem may be involved, particularly if it keeps returning or affects other areas too.
What To Do
Move your horse to the driest suitable environment you can manage and avoid letting mud sit against the skin for long periods. Gently check the area each day so you can spot swelling, heat, discharge, or spreading irritation early.
Keep the skin clean and dry without overdoing it, since repeated scrubbing or harsh washing can make things worse. If the skin is sore, cracked, or worsening, pause any home care that seems to aggravate it and get proper advice.
If the problem is mild, photos can help you monitor whether it is improving or spreading over a few days.
When To Contact A Vet
Contact your vet if the greasy heel is rapidly spreading, very swollen, hot, or painful, if your horse is lame, or if there is discharge, a bad smell, or open skin. You should also call if your horse seems dull or unwell, or if the problem is not improving with sensible home care.
Vet advice is especially important if the area looks infected or your horse has repeated episodes, because ongoing skin disease sometimes needs a proper diagnosis rather than repeated cleaning alone.
Products That May Help
For horses that get greasy heel linked with wet, dirty, or irritated skin, a gentle washing routine may help support day-to-day hygiene as part of your management plan.
