Overview
Crusty, flaky or debris-covered ears in horses are often down to everyday dirt, sweat, dead skin or irritation. Sometimes it can be linked to flies, mites, skin sensitivity or a minor skin issue around the ear, so it’s worth checking the area calmly rather than assuming it’s just mud or dust.
Things To Check
1. Check whether the ears look worse after turnout, grooming, exercise or being in the stable.
2. Look for redness, swelling, heat, broken skin, scabs or any discharge.
3. Notice whether your horse is rubbing the ears, shaking the head, flicking the ears back or seeming bothered when touched.
4. Check for flies, mites or signs of irritation around the ear edges and base of the ear.
5. See whether the crusting is limited to the outside of the ear or whether there is deeper debris, smell or discharge inside the ear.
6. Think about recent changes such as new turnout, new bedding, different grooming products or heavier sweating.
7. Check the rest of the horse’s skin and coat for dandruff, scurf, sores or itchiness in other areas.
Common Causes
The most common cause is simple build-up of dirt, sweat and dead skin, especially in horses that are out in all weathers or have a thick coat.
Flies and other insects can irritate the ear area and lead to rubbing, debris and flaky skin.
Skin sensitivity, mild dermatitis or a reaction to grooming products can also leave the ears looking crusty or scurfy.
Less commonly, mites or another skin problem may be involved, particularly if the ears are very itchy, scabbed or persistently dirty despite regular cleaning.
What To Do
Start with a calm visual check and gentle grooming around the outside of the ears. If the debris is just surface dirt or loose flakes, careful wiping with a soft, damp cloth may be enough.
Keep an eye on whether the problem returns after turnout, sweating or grooming, as that can help you spot a pattern.
Try to avoid picking at crusts or putting anything deep into the ear, as that can make irritation worse.
If your horse is prone to sweating or getting dusty, a steady grooming routine and sensible stable or field hygiene may help reduce build-up.
If the ears stay crusty, become sore, smell unusual or your horse seems uncomfortable, it’s sensible to get veterinary advice so the cause can be checked properly.
