Overview
Call the vet if your horse’s ears are dirty or irritated and the problem is not improving, looks painful, or comes with redness, swelling, discharge, bad smell, scabs, head shaking or sensitivity when you touch them. A bit of dirt or mild irritation is often linked to flies, grooming, sweat or simple debris, but ongoing ear problems can also point to skin irritation or infection.
Things To Check
1. Check when the problem seems worse, such as after turnout, grooming, exercise or fly exposure.
2. Look closely at both ears for redness, swelling, heat, discharge, scabs, hair loss or broken skin.
3. Notice whether your horse is head shaking, rubbing, tilting the head or objecting to touch around the ears.
4. Check for dirt, waxy build-up, sweat or clumped hair that may be collecting inside or around the ear.
5. Think about recent changes such as new turnout, heavy fly pressure, clipping, washing or new grooming habits.
6. See whether one ear is affected or whether both ears look the same, which can help you describe the problem to your vet.
7. Watch for any smell, discharge or crusting, as these can suggest the ear needs a proper assessment.
Common Causes
The most common causes are dirt, sweat, wax build-up and irritation from flies or grooming. Some horses are simply more sensitive around the ears, especially in summer or when fly pressure is high.
Less commonly, the problem can be linked to skin irritation, minor scratches, trapped debris, or an ear infection. If the ear looks sore, swollen or keeps getting worse, it’s best not to keep guessing.
What To Do
Start by checking the ears in good light and gently removing loose dirt from the outside only. Use calm, careful grooming and avoid poking inside the ear canal.
Keep notes on when the problem happens, what it looks like and whether anything makes it worse. That makes it easier to spot a pattern and to explain it clearly if you do need advice.
If flies seem to be a factor, focus on sensible field and stable management during the season, including routine fly control and keeping the horse as comfortable as possible when handled or turned out.
When To Contact A Vet
Contact your vet if the irritation is severe, there is discharge, swelling, bad smell, obvious pain, repeated head shaking, or the ear is becoming more inflamed. Also get advice if the problem lasts more than a few days, keeps returning, or your horse will not let you near the ears.
Seek prompt vet help if there is sudden marked swelling, bleeding, a cut you can’t assess properly, or any change in balance, behaviour or how your horse is using the head.
