Overview
If your horse’s wound is healing slowly, it’s often down to the wound being deeper than it first looked, getting rubbed or contaminated, or the area staying damp and dirty. Some wounds also simply take longer because of their location, especially on lower legs. It’s worth keeping a close eye on it, but slow healing doesn’t automatically mean something serious.
Things To Check
1. Check whether the wound is on a lower leg, near a joint, or in an area that bends and rubs as your horse moves.
2. Look closely for redness, swelling, heat, discharge, scabbing that keeps breaking down, or any bad smell.
3. Note whether the wound keeps getting knocked by turnout, stable walls, rugs, boots, tack or grooming.
4. Check if the area is staying wet, muddy, dusty or dirty, which can slow normal healing.
5. Think about whether the wound is being cleaned too often or with harsh products, as this can irritate the skin.
6. Watch for pain, a change in lameness, reluctance to move, or if your horse is protecting the area.
7. Consider whether flies, scratching or rubbing are disturbing the wound and opening it back up.
8. Check your horse’s general condition, including appetite and behaviour, as poor overall health can sometimes affect healing.
Common Causes
The most common reason is simple delay from repeated irritation. A wound that keeps rubbing, getting dirty or being re-opened often heals more slowly than one that stays clean and undisturbed.
Location is another common factor. Wounds on the lower limb usually heal more slowly than those on better-muscled areas because there is less soft tissue and more movement.
Infection can also slow healing, especially if you’re seeing heat, swelling, discharge or worsening tenderness. Even without obvious infection, some wounds stay inflamed if the skin keeps getting wet or contaminated.
Less commonly, a wound may not heal well because it’s deeper than it first appeared, there’s a small foreign body in it, or the surrounding skin is bruised or damaged.
What To Do
Keep the wound as clean as you reasonably can, but avoid overhandling it. A gentle, consistent routine is usually more helpful than frequent fiddling.
Reduce anything that’s likely to rub or dirty the area, and think about whether turnout, stable management or grooming could be making it worse. If the wound is on a lower leg, try to keep the area dry and watch closely for swelling or heat.
Take a clear photo each day so you can judge whether it is improving, staying the same or getting worse. Small changes are easier to spot when you compare images rather than memory.
If the wound keeps reopening, seems painful, or is not clearly improving after a few days, it’s sensible to ask your vet for advice.
