Overview
A pastern wound may heal slowly because that area is easy to knock, stays damp or muddy, or keeps getting irritated by movement and dirt. Sometimes it’s just a minor wound that needs steady care, but delayed healing can also happen if the wound is deeper than it first looked or if infection is developing.
Things To Check
1. Check whether the wound keeps getting wet, muddy or rubbed by boots, bandages, fencing or nearby legs.
2. Look closely for redness, swelling, heat, discharge, smell or increasing tenderness around the pastern.
3. See whether the horse is still comfortable walking and turning, or if they’re becoming more reluctant to bear weight.
4. Check if there’s a scab that keeps lifting off, or a wound that opens again after it seems to start closing.
5. Consider whether flies, insects or rubbing are disturbing the area, especially in warmer weather.
6. Look at the position of the wound. Wounds over joints, creases or areas that move a lot often heal more slowly.
7. Think about whether the horse has any underlying issues that may affect healing, such as poor circulation, thin skin, mud-related irritation or a history of proud flesh.
Common Causes
The most common reason is repeated irritation. The pastern is a low, exposed area, so even a small wound can keep reopening with movement, mud or rubbing.
Damp, dirty conditions can also slow healing because the skin stays soft and more easily damaged. Muddy turnout is a frequent culprit.
Another common cause is infection or low-grade inflammation. You might notice discharge, smell, heat or swelling, but sometimes the signs are subtle at first.
If the wound crosses a crease, joint or area that bends a lot, healing can take longer because the skin is under constant movement.
Less commonly, the wound may be deeper than it first appeared, or there may be proud flesh developing on a wound that hasn’t been settling down.
What To Do
Keep the area as clean and dry as you realistically can. If mud is a problem, try to reduce exposure and avoid letting dirty bedding build up around the leg.
Check the wound at the same time each day so you can spot changes early. Taking a quick photo can help you judge whether it’s improving or not.
Be gentle with washing and handling. Repeated scrubbing can slow healing if the skin is already sore or fragile.
Make sure any turnout, bandaging or leg protection isn’t creating extra rubbing. If the wound looks worse after exercise or turnout, that pattern is worth noting.
If the wound isn’t clearly improving after a few days, or it keeps reopening, it’s sensible to get it assessed rather than hoping it will sort itself out.
When To Contact A Vet
Contact your vet if the wound is getting more swollen, hot, painful or smelly, if there’s discharge, if the horse is lame, or if the wound is over a joint and not improving. A vet should also check any wound that keeps opening, looks deep, or hasn’t started to settle after several days of sensible home care.
