Overview
If your horse's cut is making a bad smell, it usually means the wound is dirty, staying too wet, or developing an infection. A smell isn't something to ignore, but it doesn't always mean there is a serious problem. The main job is to check the wound carefully, keep it clean and watch how it changes over the next day or two.
Things To Check
1. Check where the smell is coming from and whether it gets stronger after exercise, turnout or bandage changes.
2. Look closely for redness, swelling, heat, discharge, pus, scabs or skin that looks soggy.
3. See whether the cut is open, gaping, covered in mud or rubbed by tack, rugs or stable fittings.
4. Notice if your horse is sore to touch, lame, holding the area away, or reacting more than you'd expect.
5. Check whether flies, wet bedding or muddy conditions may be keeping the area irritated or contaminated.
6. Look at the size and depth of the cut and whether it's starting to look worse rather than better.
7. Make a note of any change in your horse's behaviour, appetite or general brightness.
Common Causes
The most common reason is dirt or moisture trapped in the wound, especially if the cut has been in a muddy field, under a bandage, or in a spot that gets rubbed.
A smell can also come from normal wound fluids that have started to break down, particularly if the area has been left too long before cleaning or drying properly.
In some cases, infection may be developing. This is more likely if there is swelling, heat, increased pain, thick discharge or the wound seems to be getting worse.
Less commonly, dead tissue or a deeper wound pocket can cause a stronger smell, especially if the outside of the cut looks small but the area underneath is more involved.
What To Do
Gently assess the wound and remove loose dirt if you can do so safely. Keep the area clean and dry, and avoid putting anything harsh onto the cut unless you know it is suitable for horse wounds.
If the skin around the cut is wet, muddy or greasy, improve the surroundings as much as possible by using cleaner bedding, reducing mud contact and checking whether rugs, boots or tack are rubbing the area.
Keep a close eye on the smell, the amount of discharge and how the skin looks over the next 24 to 48 hours. Take a photo if you want to compare changes.
If the wound is in a place that moves a lot, or it keeps getting dirty, it may need more careful protection and monitoring than a simple scrape elsewhere on the body.
