Overview
If your horse’s wound isn’t healing after several days, it could be getting irritated, staying too wet or dirty, or developing an infection. Some wounds simply take longer than expected, especially if they’re on a moving area like a leg, but ongoing redness, swelling, heat or discharge means it’s worth paying closer attention.
There are several possible reasons, and you usually can’t tell the full picture from appearance alone. The aim is to keep the wound clean, watch for changes and spot the point where it needs veterinary input.
Things To Check
1. Check whether the wound is getting bumped, rubbed or reopened during turnout, work or grooming.
2. Look for redness, heat, swelling, discharge, bad smell or increasing tenderness around the area.
3. Note whether the wound is wet, muddy or covered in debris, as this can slow healing.
4. Check if the horse is more uncomfortable than before, especially if the area is on a leg or near a joint.
5. See whether there’s a scab forming and then breaking down again, which can happen if the area keeps being disturbed.
6. Check for flies, licking or rubbing that might be keeping the skin irritated.
7. Watch for any general changes such as dullness, reduced appetite or not wanting to move normally.
Common Causes
The most common reason is that the wound is being repeatedly irritated, either by movement, dirt, wet conditions or the horse rubbing it.
Another common cause is infection, which can make the wound look wetter, smell unpleasant, become more swollen or stay painful.
Some wounds heal slowly because they’re deeper than they first appeared, or because there’s a small amount of debris still in the wound.
Less commonly, wounds on lower limbs can be slow to settle because that area moves a lot and can swell more easily.
In a few cases, what looks like a simple wound may need a vet to check for a more complicated issue underneath, especially if it keeps reopening or doesn’t improve.
What To Do
Keep the area as clean and dry as you reasonably can, and avoid using harsh or random products on it.
If the wound is dirty, gently remove surface dirt with suitable first aid care, then monitor it for changes rather than constantly picking at scabs.
Reduce anything that may be irritating it, such as mud, flies, rubbing tack or heavy exercise, until it starts to settle.
Take a photo once a day if you can. That makes it much easier to notice if the wound is improving, staying the same or getting worse.
If the wound is on a leg, keep an eye on swelling, heat and how the horse is moving. If it’s not clearly improving after a few days, don’t just leave it indefinitely.
When To Contact A Vet
Contact your vet if the wound is getting more swollen, hot, painful or smelly, if there’s pus or persistent discharge, or if the horse seems unwell. You should also call if the wound is over a joint, looks deep, keeps reopening, or hasn’t shown any improvement after several days of sensible home care.
Products That May Help
For everyday wound and minor skin care, a sensible first aid routine can help you keep the area clean and easier to monitor while it heals.
