Overview
Repeated ear rubbing in horses is usually a sign that something is irritating the ear or the area around it. Common causes include flies and other insects, ear mites, dirt or wax build-up, skin irritation, and sometimes a problem deeper in the ear that needs a vet to check.
You can often spot clues yourself by looking at when the rubbing happens and whether there are visible changes, but you usually can't tell the exact cause just by watching. Ear mites are one possible cause, especially if there’s itching, head shaking or dark debris, but they’re not the only one.
Things To Check
1. Check whether the rubbing happens more after turnout, in windy weather, or during fly season.
2. Look closely for redness, swelling, broken skin, discharge, scabs or heat around the ear.
3. Notice whether your horse is shaking its head, tilting it, or avoiding being touched near the ears.
4. Check for dirt, wax or dark debris around the outer ear flap, without putting anything down into the ear canal.
5. See whether one ear is affected or whether both ears are being rubbed.
6. Think about any recent changes such as new bedding, grooming products, turnout routine or tack that may be rubbing the area.
7. Watch for signs of flies or midges bothering your horse, especially if the rubbing is worse outdoors.
8. Note whether the behaviour is occasional or happening often enough to be a clear pattern.
Common Causes
Flies and midges are a very common reason for ear rubbing, especially in warmer months or if your horse is standing still outdoors.
Skin irritation can also play a part. This might come from grooming friction, sweat, dust, hay, bedding, or a reaction to something in the horse's environment.
Ear mites are another possible cause. They can lead to itching, head shaking, rubbing and sometimes dark, crumbly debris, although other ear problems can look similar.
Wax build-up or dirt in the outer ear can make the area feel uncomfortable and prompt rubbing, particularly if your horse is already sensitive.
Less commonly, ear rubbing may be linked to an infection, a small foreign body, or pain somewhere else around the head or neck.
What To Do
Start by keeping a simple note of when the rubbing happens and what seems to make it worse. That pattern can be helpful if you need to speak to your vet later.
Keep the area around the ears clean and dry, and use gentle grooming around the head so you don't add more irritation. Avoid putting anything into the ear canal unless you've been shown how to do that safely.
If flies seem to be making it worse, focus on sensible summer management such as reducing exposure at peak times and keeping the horse comfortable in turnout and at rest.
If the skin is already sore, try to prevent further rubbing on gates, rugs or tack while you monitor it. If the rubbing continues, becomes more frequent, or comes with discharge, pain or head shaking, ask your vet to check the ears.
When To Contact A Vet
Contact your vet if the ear rubbing is persistent, the horse seems painful, there’s discharge or a bad smell, or you notice head shaking, swelling, scabs or a change in behaviour. Ear problems can be difficult to assess without looking inside the ear properly.
It’s also sensible to get advice if you suspect ear mites or the problem doesn’t improve with basic environmental checks.
