Why is there discharge from my horse’s hoof after a puncture?

Read time: 3 minutes

Overview

Discharge from a horse’s hoof after a puncture usually means the hoof is trying to drain fluid from the injury, or that dirt and bacteria have got into the wound. It can also happen if the tract is still open and working its way to the surface. Because punctures in the hoof can behave differently depending on where they are and how deep they go, it’s worth taking it seriously even if your horse seems fairly comfortable.

Things To Check

1. Look at the colour and amount of discharge. Clear or slightly cloudy fluid can mean drainage, while thicker, yellow, green or smelly discharge is more concerning.

2. Check whether the hoof feels warmer than the others, or whether there’s any new sensitivity when your horse turns or walks on firm ground.

3. Inspect the puncture area for swelling, a blackened track, dirt packed into the hole, or any sign that the wound is still open.

4. Watch your horse move off on a straight line and then on a circle, if it’s safe to do so, to see whether there’s any obvious lameness or shortness of stride.

5. Notice whether your horse is more reluctant to put weight on the foot, stands differently, or keeps the leg resting more than usual.

6. Check the surrounding environment, especially mud, wet turnout, dirty bedding or manure, as these can make contamination more likely.

7. Look for any change in general behaviour, such as dullness, reduced appetite or repeated shifting of weight.

Common Causes

The most common reason is that the puncture is draining as the hoof reacts to the injury. The hoof capsule is tight, so fluid can track out through the hole rather than spreading freely.

Another common cause is contamination. Dirt, bedding or bacteria may have entered the puncture, which can lead to an infection or an abscess forming later on.

Less commonly, the discharge may reflect a deeper tract or internal damage that is still working its way out. In some cases, a small-looking puncture can be more significant than it first appears, especially if it’s near the sole or frog.

Sometimes the discharge is from a wound that has reopened because the hoof has been wet, dirty or picked at, which can make healing slower and messier.

What To Do

Keep the hoof as clean and dry as you can without fussing with it. If you’ve already been given specific advice by your vet or farrier, follow that first.

Check the horse’s comfort and watch for changes over the next 24 hours. A photo of the hoof and a note of the discharge amount, colour and smell can help you spot whether things are improving or worsening.

Reduce exposure to mud, deep bedding or dirty turnout if you can do so safely. A clean, dry standing area is often easier to manage while the hoof is healing.

Do not dig into the puncture or try to probe the wound yourself, as that can make the problem harder to assess and may introduce more contamination.

If the hoof changes quickly, becomes more painful, or you’re unsure how deep the puncture was, get professional advice rather than waiting for it to settle.

When To Contact A Vet

Contact your vet promptly if the discharge is thick, smelly, bloody or increasing, or if your horse is lame, very sore, or the hoof is getting hotter or more swollen. A puncture wound in the hoof can sometimes need assessment to check how deep it goes and whether further treatment is needed.
