Overview
If your horse’s wound has black or dead-looking tissue, check the wound size, smell, heat, swelling, discharge and how your horse is moving or reacting to it. Black areas can sometimes be dried blood, scab, bruised tissue or dead tissue, so it’s worth keeping a close eye on it rather than assuming it’s one thing or another.
Things To Check
1. Check whether the dark area is dry and stuck to the wound, or soft, wet and spreading.
2. Look for heat, swelling, redness or tenderness around the wound edges.
3. Notice any discharge, bad smell or changes in the amount of fluid coming from the wound.
4. Compare the area with nearby skin to see if the tissue looks bruised, leathery or clearly separated from healthy tissue.
5. Check whether your horse is more sore than expected, shorter in stride or reluctant to move that part of the body.
6. Make sure the wound is not getting larger, deeper or more open over time.
7. Watch for general signs your horse feels unwell, such as dullness, fever, reduced appetite or being less willing to be handled.
Common Causes
The most common explanation is a wound that’s formed a scab or dried blood, which can look black at first. Bruising around the injury can also make tissue appear darker than expected.
If the area is soft, smelly, wet or spreading, it could be infected or contain tissue that’s no longer healthy. Dirt, mud and trapped discharge can also make a wound look worse than it really is.
Less commonly, a deeper wound can damage blood supply to the area, which may lead to tissue death and delayed healing. That needs careful assessment, especially if the wound is on a lower limb or near a joint.
What To Do
Keep the wound clean and watch for changes in size, colour, smell and discharge. If you’re able to safely do so, gently remove surface dirt around the wound without disturbing anything that looks firmly attached.
Keep the horse in a cleaner, drier environment if possible, as mud and muck can make wound care harder. Avoid picking at black tissue, cutting anything away or using harsh products unless your vet has already advised you to do that.
Take clear photos if you can, so you can compare the wound over the next day or two. If it looks worse, becomes more painful, smells bad or your horse seems off, it’s sensible to get veterinary advice.
When To Contact A Vet
Contact your vet if the black area is spreading, the wound is deep, the leg is swollen or hot, there’s bad-smelling discharge, or your horse is lame or clearly uncomfortable. A vet should also assess it if the wound is near a joint, tendon, eye or chest, or if you’re not sure whether the tissue is dead or just scabbed over.
It’s especially important to get help promptly if the wound is getting worse rather than better over 24 to 48 hours.
Products That May Help
A general horse first aid and wound care collection can be useful for keeping basic cleaning and routine wound management supplies together, so you’re not looking for things in a hurry when a wound needs checking.
