Overview
Repeated ear irritation in horses is often caused by flies, dust, grooming habits, trapped sweat or a skin sensitivity rather than anything more serious. In many cases, the main clues are when it happens, what the ears look like and whether the horse is also rubbing, head shaking or reacting to touch.
It’s worth checking the ears carefully, but don’t try to rule out all causes yourself if the irritation keeps coming back or seems to be getting worse.
Things To Check
1. Check whether the irritation happens after turnout, exercise, grooming or fly activity.
2. Look for redness, heat, scabs, broken skin, swelling or discharge around the ear.
3. Notice if the horse is shaking the head, rubbing the ears or resisting headcollar or bridle use.
4. Check for dirt, loose hair, dried sweat or bedding dust around the ear base and outer ear.
5. Think about recent changes in weather, flies, turnout, feed, grooming products or tack.
6. See whether one ear or both ears are affected, as that can give a clue about local irritation or a more general skin issue.
7. Check whether the horse seems painful when the ears are touched or handled.
Common Causes
Flies and other insects are a very common cause, especially in warmer months or around hedges, muck heaps and standing water. Horses may react by twitching, rubbing or shaking their heads.
Dust, sweat and grooming debris can also build up around the ears, particularly after exercise or clipping. This can leave the skin feeling sore or itchy.
Skin sensitivity or mild irritation from grooming, fly sprays, shampoos or tack contact can also play a part. Sometimes the issue is more obvious after a change in routine or product.
Less commonly, repeated irritation may be linked to a skin infection, ear mites, a foreign body or another ear problem that needs a closer look.
What To Do
Start by keeping the ears clean and dry as part of your normal routine, using gentle handling and avoiding rough cleaning inside the ear.
Reduce the things that seem to trigger it where you can, such as fly pressure, dusty bedding or products that leave the skin looking sore.
Keep a simple note of when it happens, what the ears look like and anything that seems to make it better or worse. That can be very helpful if the problem keeps recurring.
If the horse is happy to be handled, check the ears regularly for changes rather than waiting until the irritation becomes obvious again.
When To Contact A Vet
Contact your vet if the irritation keeps coming back, there’s discharge, swelling, a bad smell, marked pain, head shaking that doesn’t settle, or the horse won’t let you touch the ears. These signs can suggest something that needs proper examination rather than routine care alone.
Products That May Help
If flies seem to be part of the problem, a summer care routine can be useful alongside sensible turnout and grooming habits. The collection below may help support day-to-day management during fly season.
