Overview
If your dog’s ears keep getting dirty, there’s usually an ongoing reason rather than just a one-off build-up. It could be wax, moisture, skin irritation, a little debris from the environment, or something more persistent affecting the ear canal. The main thing is to check what the dirt looks like, how often it returns, and whether your dog seems bothered by it.
Things To Check
1. Check whether the ears look the same on both sides, or if one ear is consistently worse.
2. Look for redness, swelling, a bad smell, discharge, scabs, heat, or signs of soreness.
3. Notice whether your dog is scratching, shaking their head, rubbing their ears, or reacting when you touch them.
4. Think about whether the problem appears after swimming, bathing, walks in long grass, or time outdoors in muddy or dusty areas.
5. Check how the ear flap sits. Floppy ears and very hairy ears can hold more moisture and debris.
6. Look at the colour and texture of the debris. Dry brown wax, pale flakes, dark discharge and wet debris can point to different causes.
7. Make sure grooming products, shampoo, or water are not being left in the ear after washing.
Common Causes
The most common cause is normal wax build-up, especially in dogs with hairy or floppy ears. Some dogs simply need more regular checking and cleaning than others.
Moisture trapped in the ear after swimming, bathing or wet weather can also lead to repeated dirtiness and a musty smell.
Skin irritation or an ear infection may cause wax, discharge and debris to build up again and again. Allergies can sometimes play a role too, especially if the ears are also itchy or inflamed.
Less commonly, the ear canal shape, excess hair, a foreign body, or an underlying skin problem can make the issue keep coming back.
What To Do
Keep a simple eye on how often the ears need attention and whether anything makes them worse. A quick look once or twice a week is often enough for many dogs, unless your vet has advised a different routine.
After bathing or swimming, dry the outer ear gently. Avoid putting anything deep into the ear canal, and don’t use cotton buds inside the ear.
If the dirt is mild and your dog is comfortable, regular home ear checks and gentle cleaning of the outer ear may help with routine hygiene. If it keeps coming back, note the colour, smell and timing so you can explain the pattern clearly if you do speak to your vet.
If your dog has floppy ears, lots of ear hair, or is prone to getting wet or muddy, keeping those areas as dry and clean as practical can help reduce repeated build-up.
When To Contact A Vet
If the ears are smelly, sore, red, swollen, very itchy, or producing discharge, it’s a good idea to get them checked. You should also contact your vet if the problem keeps returning, only affects one ear, or your dog seems uncomfortable when their ears are touched.
