Overview
Call your vet if the wound is getting more swollen, painful, hot, smelly, or is oozing pus, or if your horse is lame, unwell, or the wound is near a joint, tendon, or the lower leg. Small surface wounds can sometimes be managed with careful cleaning and monitoring, but leg wounds can become a problem quickly, so it’s sensible to get advice sooner rather than later if anything looks worse.
There can be several reasons a wound looks infected, including trapped dirt, repeated knocking, insects, mud, or a deeper injury than first thought. You can check the basics at home, but you can’t rule out a more serious issue just by looking at it once.
Things To Check
1. Check whether the wound is getting larger, wetter, more swollen, or more painful from one day to the next.
2. Look for heat, redness, discharge, bad smell, scabbing that keeps breaking open, or pus.
3. See if your horse is lame, short-striding, reluctant to turn, or sensitive when the leg is touched.
4. Check whether the wound is over a joint, tendon, cannon bone, or very close to the hoof.
5. Think about whether mud, wet turnout, flies, or repeated knocking might be slowing healing.
6. Note whether your horse seems dull, off their feed, or generally not themselves.
7. Watch for swelling that is spreading up or down the leg rather than staying local to the wound.
Common Causes
The most common reason is a simple cut or graze that has become contaminated with dirt, mud, or bacteria.
Sometimes the wound keeps being irritated by wet ground, rubbing, movement, or flies, so it doesn’t settle properly.
A deeper puncture or a wound close to a sensitive structure can also look like a minor skin injury at first.
Less commonly, swelling or discharge may be linked to a more involved injury underneath the skin, which is why leg wounds are worth taking seriously if they’re not improving.
What To Do
Keep the area as clean as you can using routine first aid and avoid picking at scabs or forcing dirt out if it’s stuck. If the wound is dirty, gently remove loose debris and keep a close eye on it over the next 24 to 48 hours.
Reduce mud, wet turnout, and anything that could keep irritating the area. If possible, give your horse a clean, dry place to stand and monitor the leg at least once or twice a day.
Take a photo and note the size, heat, swelling, discharge, and how your horse is moving so you can spot changes quickly.
If it’s not clearly improving, or you’re unsure how deep it is, it’s sensible to speak to your vet.
When To Contact A Vet
Contact your vet promptly if the wound is swollen, hot, painful, smelly, or producing discharge, or if your horse is lame, dull, or the wound is near a joint, tendon, or the lower leg. Get help sooner if the swelling is spreading, the wound is opening up, or there’s no clear improvement after a day or two of careful monitoring.
Products That May Help
A sensible wound care routine can make it easier to keep an eye on the area and manage minor knocks and grazes while you’re waiting for a wound to settle.
