Overview
If a horse’s wound keeps reopening, it’s often because the area is being rubbed, stretched, knocked or kept too wet. Sometimes the wound is also not fully settled underneath the surface, so it opens again with movement or pressure. There can be several causes, so it’s worth checking the wound carefully rather than assuming it’s just a slow-healing scratch.
Things To Check
1. See whether the wound opens more after turnout, exercise, rug changes or grooming.
2. Look for swelling, heat, redness, discharge, smell or increasing tenderness around the area.
3. Check if the wound sits over a joint, a moving area, or somewhere that gets bent and stretched a lot.
4. Think about whether tack, rugs, stable fittings, fencing or field conditions could be rubbing it.
5. Notice whether flies, mud, wet bedding or dirt seem to make the area worse.
6. Check if your horse is licking, biting or scratching at the wound.
7. Watch for any change in lameness, stiffness or general behaviour.
Common Causes
The most common reason is simple irritation from movement, rubbing or knocking the same spot repeatedly. A wound over a busy area can split open again before the skin has fully knit together.
Another common cause is contamination from dirt, mud or damp conditions. Even if the wound looks small, a dirty or wet environment can make healing slower and the skin more fragile.
Sometimes there is a mild infection or deeper tissue irritation underneath the surface. That can make the area ooze, swell or break down again, especially if it has already been reopened a few times.
Less commonly, the wound may be affected by foreign material, a small abscess, or a healing problem that needs more specific treatment.
What To Do
Keep the wound as clean as you can using your normal, sensible first aid routine, and avoid picking at scabs unless you have been advised to do so. If the area is likely to rub, look at whether turnout, rugs, boots, tack or stable fittings could be contributing.
Try to keep the horse’s environment as clean and dry as possible. Reducing mud, wet bedding and repeated knocks can make a real difference to how often a wound reopens.
Take a photo each day so you can compare changes in size, swelling and discharge. If it keeps reopening, that pattern is useful information if you do need to speak to a vet.
When To Contact A Vet
Contact your vet if the wound keeps reopening and is getting larger, more painful, more swollen or more dirty. It’s also sensible to call if there’s heat, discharge, a bad smell, lameness, or if the wound is over a joint, on the lower leg, or not improving with careful home management.
