Overview
Excessive ear wax in dogs usually means the ear is producing more wax than normal, or the ear canal is being irritated. It can happen for fairly routine reasons, but it can also go along with an ear problem that needs attention. The wax itself is a clue, not a diagnosis.
Things To Check
1. Notice whether only one ear is affected or both, as that can help you spot a pattern.
2. Look for changes in colour, smell, swelling, redness, discharge, scabs or visible soreness around the ear.
3. See if your dog is shaking their head, scratching at the ear, rubbing against furniture or holding the ear differently.
4. Think about whether the wax seems worse after swimming, bathing, wet walks, grooming or time outdoors.
5. Check whether your dog seems uncomfortable when you touch near the ear or when they chew.
6. Note whether this is a new change, a recurring issue, or something that has slowly built up over time.
7. Look at the ear flap and the skin around it for signs of general skin irritation, dandruff or hair loss.
Common Causes
The most common reasons are normal wax build-up, trapped moisture, dirt, or mild irritation from grooming, swimming or an active dog life.
Allergies are another common cause, especially if your dog also has itchy skin, paw licking or recurrent ear trouble.
Ear mites, yeast or bacterial ear infections can also lead to more wax, often with smell, redness or discomfort.
Less commonly, a foreign body, a narrowing ear canal, or a growth in the ear can affect drainage and make wax build-up worse.
What To Do
Start by monitoring the ear for a few days if your dog seems otherwise well and there are no obvious signs of pain.
Keep the ear dry after washing or swimming, and avoid putting anything into the ear canal unless you’ve been shown how to do it safely.
Do not use cotton buds inside the ear, as they can push wax deeper and irritate the canal.
If the ear is only mildly dirty and your dog is comfortable, a simple cleaning routine can help you keep track of whether things are improving or getting worse.
If the wax keeps coming back, smells bad, or comes with scratching or head shaking, arrange a vet check so the cause can be looked at properly.
Products That May Help
If your dog is prone to dirty ears, regular grooming and gentle cleaning as part of your routine may help you keep an eye on wax build-up and spot changes early.
