Why does my horse have a bite wound that keeps oozing?

Overview
If your horse has a bite wound that keeps oozing, it often means the skin is still irritated, the area is being rubbed or reopened, or the wound may be starting to become infected. Some oozing can be part of normal healing, but ongoing discharge is worth watching closely.
In many cases, the issue is something you can check at home first, such as wound location, swelling, heat, smell, movement and whether flies or mud are getting to it. If it’s not settling, or your horse seems sore, a vet may need to look at it.
Things To Check
1. Check what the discharge looks like. Clear or slightly blood-tinged fluid can be different from thick, yellow, green or smelly fluid.
2. Look for swelling, heat or increasing tenderness around the bite.
3. See whether the wound is in a place that bends, rubs or gets dirty easily, such as the legs, girth area or under the mane.
4. Check if flies, bedding, mud or turnout conditions are keeping the area irritated.
5. Notice whether your horse is licking, rubbing, stamping, flinching or reacting when the area is touched.
6. Look for any broken skin that keeps reopening, crusting over, then leaking again.
7. Check your horse’s general behaviour for signs they’re uncomfortable, quieter than usual or reluctant to move normally.
Common Causes
The most common reason is simple ongoing irritation. Bite wounds can keep weeping if the skin keeps getting disturbed by movement, mud, flies, grooming or tack.
A wound that has been lightly contaminated can also ooze for longer than expected, especially if it’s in a dirty or wet environment.
Sometimes a bite wound develops a minor infection, which may cause more discharge, heat, swelling or a stronger smell.
Less commonly, the wound may be deeper than it first looks, or there may be a small pocket of fluid under the skin that continues to drain.
What To Do
Keep the area as clean and dry as you reasonably can. If there’s mud, debris or loose hair around the wound, gently clear it away without scrubbing the skin.
Monitor the wound once or twice a day so you can spot changes in size, discharge, heat or swelling. A photo can help you compare how it’s looking.
Try to reduce anything that’s rubbing or re-irritating the area, including muddy turnout, flies, dirty bedding or tack pressure if the wound is in a tricky spot.
Avoid picking at scabs or repeatedly handling the wound unless you’re carrying out your normal care routine. If the ooze is getting worse rather than better, that’s a sign it needs more attention.
When To Contact A Vet
Contact your vet if the wound is getting bigger, the discharge becomes thick, smelly or coloured, or the area is hot, swollen or more painful. You should also call if your horse seems dull, off their food, lame, or if the bite is near a joint, eye or another sensitive area.
