Overview
If your horse has waxy build-up in its ears, the first things to check are whether the ear looks irritated, whether there’s any discharge or smell, and whether flies or rubbing seem to be making it worse. In many cases it’s linked to dirt, skin oil, insect irritation or a bit of sensitivity around the ear, but there are several possible causes.
Things To Check
1. Check whether the build-up is in one ear or both, and whether one side looks more bothered than the other.
2. Look closely for redness, swelling, broken skin, scabs, heat or a bad smell.
3. Notice whether your horse is shaking its head, rubbing its ears, stamping or seeming sensitive when touched.
4. Check if the issue is worse after turnout, after grooming, or during fly season.
5. Look for any signs of discharge that is wet, yellow, brown or thick rather than just dry waxy debris.
6. Check the skin around the ear base, face and poll for bites, irritation or areas of rubbing.
7. Think about whether anything has changed recently, such as new grooming habits, fly control, bedding, turnout conditions or feed.
Common Causes
The most common cause is simple wax, dirt and skin oil building up in a warm, hairy area that’s not always easy to clean naturally. Fly irritation and rubbing can also make the ears look waxier or cause more debris to collect.
Less commonly, the build-up may be linked to skin sensitivity, mild dermatitis, mites, or a small infection. If the ear is painful, smelly, swollen or producing discharge, that suggests it’s more than routine wax.
What To Do
Start by keeping a close eye on it for a day or two and note whether it’s improving, staying the same or getting worse. If your horse is happy to be handled, gently remove loose dirt from the outside of the ear only, using a soft cloth or routine grooming method your horse already tolerates.
Try to keep fly pressure and general irritation down, and check whether there’s a trigger such as sweaty exercise, muddy turnout or rubbing on fences or rugs. Avoid poking deep into the ear canal or trying to remove anything that seems stuck or uncomfortable.
If the waxy build-up keeps coming back, or if the ear becomes sore, smelly or more inflamed, it’s sensible to get it checked by a vet.
