Why is my horse's cut scab not healing?

Overview
If your horse's cut scab isn't healing, it's often because the area keeps getting rubbed, wet, dirty or reopened. Small cuts can look like they're improving and then stall if the skin around them is under pressure or the scab isn't staying clean and dry.
There are several possible reasons, from simple irritation to infection or a wound that's deeper than it first appeared. A quick check of the wound, the surroundings and your horse's behaviour can help you decide what to do next.
Things To Check
1. See whether the scab is being disturbed by rugs, boots, bandages, tack or stable doors.
2. Look for heat, swelling, redness, discharge, a bad smell or tenderness around the cut.
3. Check whether the wound is staying wet from rain, mud, sweat or repeated washing.
4. Notice if your horse is licking, rubbing, stamping or scratching at the area.
5. Judge whether the cut is in a place that moves a lot, such as a joint, lower leg or near the belly.
6. Think about whether flies, stable dirt or bedding could be irritating the wound.
7. Watch for any change in lameness, stiffness, appetite or overall behaviour.
Common Causes
The most common reason is simple repeated irritation. A scab can lift or crack if the area keeps moving, rubbing or getting damp.
Dirt, mud and bedding can also slow things down if the wound is not staying clean enough for the scab to settle.
Some cuts take longer because they're on a busy area like the lower leg, where the skin stretches more and healing can be slower.
Less commonly, a wound may have a small pocket of infection, a bit of debris trapped underneath, or more tissue damage than you can see on the surface.
What To Do
Keep the area as clean and dry as you reasonably can. If the wound is safe to touch, gently remove surface dirt with suitable wound care and avoid repeatedly picking at the scab.
Reduce anything that could rub, open or contaminate it, including muddy turnout, tight boots, dirty bedding or tack that touches the area.
Monitor it once or twice a day so you can spot any change in size, moisture, heat or swelling. A photo can help you tell whether it's improving.
If the scab keeps breaking down, protect the area from further irritation and keep an eye on your horse's comfort and movement.
When To Contact A Vet
Contact your vet if the wound is getting larger, more painful, hotter or more swollen, if there's discharge or smell, if your horse is lame, or if the cut is over a joint, tendon area or near the eye. It's also sensible to ask for advice if the scab hasn't improved after a few days of sensible care or you suspect something is trapped in the wound.
Products That May Help
A sensible horse care routine can make it easier to keep minor cuts and grazes clean and to monitor them day to day.
