Overview
Thick, sticky ear wax in dogs usually means the ear is producing more wax than usual, or that the wax has mixed with dirt, moisture or debris. It can happen for simple hygiene reasons, but it can also be linked to irritation, allergies, mites or an ear infection, so it’s worth checking the ear closely rather than just wiping the outside.
Things To Check
1. Check whether the wax is in one ear or both, and whether it looks the same on each side.
2. Look for redness, swelling, heat, crusting, broken skin or discharge around the ear.
3. Notice if your dog is shaking their head, scratching at the ear, or seeming uncomfortable when the ear is touched.
4. Smell the ear gently. A stronger or unpleasant smell can suggest there’s more going on than simple dirt.
5. Check whether your dog has been swimming, bathed recently, or had a lot of muddy or dusty outdoor exposure.
6. Think about whether this is a new change or something your dog gets regularly.
7. Watch for hearing changes, balance issues, or your dog tilting their head.
8. Make a note of any other skin symptoms, such as itching, paw licking or rubbing, which can go along with allergy-related ear issues.
Common Causes
The most common reason is a build-up of normal ear wax mixed with dirt, moisture or skin oils. Dogs with floppy ears, hairy ear canals or a tendency to get mucky outdoors can be more prone to this.
Another common cause is irritation from allergies or sensitivity, which can make the ear produce more wax than usual.
Ear mites are less common in adult dogs than many owners expect, but they can still cause dark, waxy debris, itching and head shaking.
An ear infection can also lead to thick, sticky discharge, especially if there’s a smell, redness, soreness or your dog is clearly bothered by the ear.
What To Do
If your dog seems otherwise well, start by checking both ears and gently cleaning only the outer part you can see with a suitable ear-cleaning routine if you already use one.
Keep the ear dry after swimming or bathing, and avoid poking into the canal with cotton buds, tissues wrapped round a finger, or anything sharp.
If the wax keeps coming back, note when it happens and whether it seems linked to wet weather, grooming, swimming or itching elsewhere on the body.
Regular ear checks are useful even when your dog’s ears look fine, because early changes are easier to spot than a full flare-up.
When To Contact A Vet
Contact your vet if the ear is painful, very smelly, swollen, hot, red or producing discharge, or if your dog is shaking their head a lot, scratching persistently, or showing balance or hearing changes. If the wax keeps coming back or only one ear is affected repeatedly, it’s sensible to get it checked.
Products That May Help
A good ear and grooming routine can make it easier to keep an eye on wax build-up and spot changes early. The right pet care collection may help support regular hygiene at home.
