Why is my horse’s cut getting bigger instead of smaller? | arlo.® Atlas

Read time: 3 minutes

Overview

If your horse’s cut is getting bigger instead of smaller, it’s often because the area is being rubbed, stretched or kept wet, or because there’s swelling around the wound making it look larger. Sometimes a wound can also become contaminated or irritated, so it’s worth checking it carefully rather than assuming it’s healing normally.

Most small cuts and grazes should start to look calmer over time, even if they don’t fully close straight away. If it’s spreading, leaking, becoming more swollen or your horse is uncomfortable, that usually means something about the healing process needs a closer look.

Things To Check

1. Check whether the cut is in a place that moves a lot, such as over a joint, on the lower leg, or somewhere likely to get knocked.

2. Look closely for redness, heat, swelling, discharge, bad smell or scabbing that keeps breaking open.

3. Think about whether the area has been rubbed by tack, rugs, mud, stable fittings or another horse.

4. See if the wound is being kept damp by wet turnout, sweat, dirty bedding or repeated washing.

5. Check whether there’s more swelling around the wound than there was before, as this can make the cut seem bigger.

6. Notice if your horse is sore, head-shy, lame or reluctant to move normally, especially if the cut is near a limb or joint.

7. Confirm whether the skin edges look pulled apart, which can happen if the wound is in a high-movement area.

Common Causes

The most common reason is simple irritation from movement, rubbing or repeated knocks. Even a small cut can seem larger if the skin keeps opening when the horse walks, bends or lies down.

Swelling around the wound is another common reason. The cut itself may not be getting much worse, but the surrounding tissue can puff up and make the area look bigger.

Wet, dirty or muddy conditions can also slow normal healing and make a wound look messy for longer. If the skin keeps softening, crusting over and reopening, it may appear to spread.

Less commonly, the wound may be contaminated or have a deeper problem underneath the surface, such as a puncture, foreign material or a wound that needs proper cleaning and support.

What To Do

Keep the area as clean and calm as you can. If the cut is dirty, gently clean away loose debris using a suitable wound-cleaning approach you’re comfortable with, then monitor it closely for changes.

Try to reduce rubbing and unnecessary movement where possible. A clean, dry environment and sensible turnout management can make a real difference to how a minor wound settles.

Take a clear photo today and compare it again in 24 hours. That makes it easier to tell whether the wound is genuinely enlarging or whether the surrounding swelling is changing how it looks.

If the cut is in a high-movement area, keeps reopening, or isn’t looking calmer after a short period of sensible home care, it’s sensible to get it checked.

When To Contact A Vet

Contact your vet if the wound is getting larger, deeper or more painful, if there’s swelling, heat, discharge or a bad smell, or if your horse is lame, unwell or the cut is near a joint, tendon or eye. A vet should also see it if it was a puncture wound, keeps reopening, or hasn’t started to improve as you’d expect.
