Overview
If your horse has a swollen cut or graze, start by cleaning it gently and checking how deep it is, how much swelling there is, and whether your horse is sore or lame. Small grazes can swell because the skin has been irritated or dirt has got into the area, but swelling can also follow a knock or hide a more significant wound.
Most minor cuts and grazes settle with sensible cleaning, monitoring and keeping the area as clean as you can. If the swelling is increasing, the wound is gaping, or your horse seems unwell, it’s sensible to get veterinary advice.
Things To Check
1. Look at the size, depth and position of the cut or graze, especially if it’s near a joint, tendon or the eye.
2. Check whether the swelling is soft, firm, warm or painful when touched.
3. Notice if there is any discharge, blood, dirt, scabbing or a bad smell.
4. Watch how your horse is moving and whether there’s any lameness or stiffness.
5. Check if the area is getting bigger rather than settling over a few hours.
6. Make sure your horse is bright, eating normally and not unusually quiet or restless.
7. Think about when the wound may have happened, such as turnout, field play, grooming or transport.
Common Causes
The most common reason is simple local irritation from a minor knock, scrape or rubbing, which can cause a bit of swelling around the wound.
Dirt, mud or debris in the graze can also make the area look puffier and slower to settle.
Sometimes a cut may be a little deeper than it first appears, or swelling may reflect bruising under the skin from the original injury.
Less commonly, a wound can become infected, especially if it’s dirty, on a lower limb, or has been left open and exposed to mud or flies.
What To Do
Clean the area gently with clean water or an appropriate wound-cleaning routine your vet has previously recommended. Keep it simple and avoid scrubbing hard, as that can irritate the skin further.
If the wound is dirty, remove loose debris carefully and dry the area as well as you can afterwards. If swelling is on a leg, a clean, well-fitted supportive bandage may be useful if you know how to apply one safely and the wound is in a place that suits bandaging.
Keep the horse somewhere clean and dry, and avoid turnout in muddy ground if you can. Monitor the size of the swelling and the horse’s comfort level at least twice a day.
If the cut was caused by a knock, check the surrounding area for heat, tenderness or extra swelling that might suggest more than a surface graze. If you’re unsure, it’s better to take photos and keep a close eye on it rather than poke at it repeatedly.
When To Contact A Vet
Contact your vet if the swelling is spreading, the wound is deep or gaping, there is pus or a strong smell, or your horse is lame, very sore, or not acting normally. You should also call if the cut is near a joint, tendon, eye or another sensitive area, or if it was caused by a dirty or rusty object and you’re unsure about tetanus protection.
Products That May Help
A practical horse care collection can be useful when you want to keep wound cleaning and general first aid supplies together, so it’s easier to stay organised if a minor graze crops up again.
