Overview
A wound that looks red and feels sore around the edges is often reacting to normal healing, but it can also mean the area is being irritated, contaminated, or becoming more inflamed. The key is to check how the wound looks, how your horse is behaving, and whether the redness is staying local or spreading.
Things To Check
1. Check whether the redness is only right at the wound edge or spreading into the surrounding skin.
2. Look for swelling, heat, discharge, scabbing, bad smell, or any tissue that looks wet and angry.
3. Note whether your horse is more uncomfortable when the area is touched, groomed, or cleaned.
4. Think about whether mud, sweat, bedding, flies, or tack could be rubbing or irritating the area.
5. Check if the wound is on a busy area such as a leg, hock, chest, or girth area, where movement can keep reopening it.
6. Watch for lameness, stiffness, or a change in how your horse is putting weight on the limb if the wound is on a leg.
7. Consider how long it has been since the wound happened and whether it has been improving, staying the same, or getting worse.
Common Causes
The most common reason is simple inflammation as the wound starts to heal. Fresh cuts and grazes often look red at the edges for a short time.
Rubbing, movement, or repeated contamination can make the skin around the wound stay sore and irritated for longer.
Dirty bedding, mud, sweat, or a wound that has not been cleaned gently can also make the edges look more inflamed.
Sometimes a small wound starts to become infected, which can cause increasing redness, heat, pain, swelling, and discharge.
Less commonly, a wound can have deeper damage than it first appears, especially if it is near a joint or on a lower limb.
What To Do
If the wound is small and your horse otherwise seems well, keep the area clean, dry, and easy to monitor. Gentle cleaning and sensible hygiene are usually more useful than repeated fiddling.
Keep an eye on whether the redness settles over the next day or two, or whether it becomes more swollen, more painful, or starts to ooze.
Try to reduce rubbing or contamination by adjusting turnout, stable conditions, grooming around the area carefully, and keeping bedding and mud away from the wound where possible.
If the wound is in a place that keeps getting knocked or contaminated, it may need extra protection and closer checking as it heals.
When To Contact A Vet
Contact your vet if the redness is spreading, the area is getting hotter or more painful, there is pus or a bad smell, your horse is lame, or the wound is near a joint, tendon, eye, or another sensitive area. It’s also sensible to get advice if the wound was deep, dirty, or not improving after a couple of days.
