Overview
If your horse has a minor graze that looks infected, the safest first step is to clean it gently, keep a close eye on it, and avoid letting dirt or flies get to it. A graze can look more irritated than it really is, but increasing redness, heat, swelling, discharge or soreness can mean it needs more attention. There may be several possible causes, so it’s best not to guess.
Things To Check
1. Check whether the area is becoming more red, warm, swollen or painful compared with when you first noticed it.
2. Look for any discharge, wetness, bad smell, scabbing, or skin that’s starting to break down.
3. See if your horse is bothered when you touch the area, move the skin, or brush nearby.
4. Check whether the graze is in a place that gets muddy, sweaty, rubbed, or exposed to flies.
5. Note whether your horse is otherwise bright, eating normally and moving comfortably.
6. Think about when it appeared and whether it has changed after turnout, exercise, grooming or washing.
7. Check if there are any signs of deeper injury, such as a puncture, gaping skin, or swelling spreading beyond the graze.
Common Causes
Most minor grazes that seem to be getting worse are due to everyday contamination from dirt, bedding or mud, especially if the area stays damp.
Fly irritation, rubbing or repeated minor trauma can also make a small graze look inflamed and slow to settle.
Sometimes a graze has been irritated by too much washing, harsh products, or friction from tack, rugs or fencing.
Less commonly, the area may have a deeper wound, a small foreign body, or an early skin infection that needs veterinary assessment.
What To Do
Gently clean the area with clean water or a vet-approved wound care routine, then pat it dry rather than rubbing it.
Keep the horse in a cleaner, drier environment if you can, and reduce exposure to mud, flies and repeated rubbing while it heals.
Don’t pick off scabs or keep washing the graze repeatedly, as that can slow the skin’s natural healing.
Monitor it at least once a day, and take note of any change in size, heat, swelling, pain or discharge.
If the graze is very small and your horse is otherwise well, a little careful observation can be enough at first. If it’s not improving, or it starts to look more inflamed, it’s sensible to get veterinary advice.
When To Contact A Vet
Contact your vet if the graze is getting more swollen, hot, painful or weepy, if there’s a bad smell, if the skin is breaking down, or if your horse seems unwell or lame. You should also call if the wound is near a joint, tendon or eye, if you’re unsure how deep it is, or if it isn’t improving within a day or two of sensible basic care.
Products That May Help
If you’re dealing with small cuts and grazes, a general horse care collection can be useful for keeping your routine simple and organised while you monitor the area.
