Overview
If your horse has greasy heel and the lower leg is swollen, it’s worth taking it seriously but staying calm. Greasy heel often happens alongside wet, muddy or dirty conditions, and the swelling may simply be from skin irritation or from the leg having been left damp. There can be several possible causes, so the aim is to check the area carefully, keep it clean and dry, and watch how it changes.
Things To Check
1. Check whether the swelling is in one leg or both, and whether it feels soft, firm, warm or sore.
2. Look closely for scabs, crusting, broken skin, discharge, redness or any smell from the skin.
3. Notice if your horse is lame, short-striding, reluctant to turn, or more sensitive when the leg is handled.
4. Think about recent turnout, muddy fields, long grass, wet bedding, sweating under boots, or washing that may have kept the skin damp.
5. Check whether the swelling improves after stabling, gentle walking or drying, or whether it is staying the same or getting worse.
6. Compare the affected leg with the others so you can see whether the size, heat or skin changes are clearly different.
7. Look for any cuts, bites or small knocks that might have irritated the skin and made the swelling worse.
Common Causes
The most common cause is skin irritation linked to damp, dirty or muddy conditions, which can make greasy heel more noticeable. Scratching, rubbing and repeated wetting can also inflame the skin and lead to swelling in the lower leg.
Sometimes the swelling is part of a more general skin reaction, or it may be associated with a minor wound, mud fever-type irritation or infection starting in the skin. Less commonly, swelling can be linked to a deeper problem in the leg, so it’s important not to assume it’s only the skin if the signs are more than mild.
What To Do
Gently clean the area if it’s dirty, then dry it well. Avoid aggressive scrubbing, because sore skin can get more irritated. If the skin is very crusty, soften what you can with careful washing rather than picking scabs off roughly.
Keep the leg as dry and clean as possible. That may mean adjusting turnout, avoiding deep mud where you can, and making sure stable bedding is clean and not too damp. If your horse is comfortable, a little controlled movement can sometimes help the swelling settle.
Monitor the leg closely over the next day or two. Take a photo if that helps you compare changes. If the swelling, heat, pain or skin damage is increasing, or if your horse seems unwell or lame, get veterinary advice.
