Overview
If a horse’s wound looks infected and is healing slowly, the safest first step is to keep it clean, limit contamination and watch it closely. A slow-healing wound can have several causes, including ongoing dirt exposure, movement in a high-motion area, flies, repeated rubbing or an underlying issue that needs veterinary attention.
Try not to assume it’s only a minor problem if it’s getting wetter, smellier or more swollen. At the same time, many wounds do improve with sensible local care and a bit of time, especially if they’re kept clean and protected from further irritation.
Things To Check
1. Check whether the wound is becoming more red, swollen, warm, painful or smelly, as these changes can suggest it’s not settling well.
2. Look for discharge, pus, repeated bleeding or a scab that keeps breaking down.
3. Note whether your horse is more bothered by it, such as rubbing, stamping, flinching or moving away when you touch the area.
4. Check if the wound is in a place that moves a lot, such as near a joint, on a leg or around the heel, because these areas often heal more slowly.
5. Think about what happened before it started looking worse, including mud, turnout, grooming, exercise, flies or bandage rubbing.
6. Compare the wound with the rest of the horse’s skin and legs to see if there’s spreading swelling or other signs of irritation nearby.
7. Check your horse’s general state, including appetite, attitude and whether they seem dull or less willing to move normally.
8. If you’ve been treating it already, review whether the dressing, cleaning routine or turnout arrangements might be adding to the problem.
Common Causes
The most common reasons for a wound to heal slowly are repeated contamination, movement that keeps reopening the skin, or simple irritation from mud, bedding, tack, rugs or flies. Some wounds also stay wet or dirty because they’re in a spot that’s hard to keep clean.
Less commonly, the wound may have a deeper pocket, trapped debris or an infection that’s slowing healing. In some cases, swelling, proud flesh or an underlying problem such as skin sensitivity or poor circulation in the area can also play a part.
What To Do
Clean the area gently with a suitable wound-cleaning routine and avoid harsh scrubbing, which can irritate the tissue and delay healing. Keep the wound as clean and dry as you reasonably can, and reduce exposure to mud, manure and flies.
If the wound is in a high-movement area, check that any dressing or protection you’re using isn’t rubbing, trapping moisture or slipping. Reassess the area at least once a day so you can spot changes early.
It can also help to keep a simple note of how it looks, smells and feels each day. That makes it easier to tell if it’s improving slowly or genuinely getting worse.
When To Contact A Vet
Contact your vet if the wound is getting more swollen, painful or smelly, if there’s pus or persistent discharge, if your horse becomes dull or unwell, or if the wound is over a joint, tendon area or other high-risk location. It’s also sensible to get advice if it hasn’t shown clear improvement after a few days of careful home management.
Products That May Help
