Overview
If your dog smells cheesy around the ears, it’s often due to wax build-up, moisture, skin irritation or a yeast imbalance. It doesn’t always mean something serious, but it is worth checking the ears closely because smells often come before more obvious signs like scratching or redness.
There can be several possible causes, and the smell by itself can’t tell you exactly what’s going on.
Things To Check
1. Check whether the smell is coming from one ear or both, and whether it seems stronger after exercise, swimming or a walk in wet weather.
2. Look closely at the ear flap and the ear opening for redness, swelling, scabs, crusting, discharge or a greasy build-up.
3. Notice whether your dog is scratching, rubbing their head on furniture, shaking their head or holding the ear differently.
4. Gently check if the ear feels hotter than usual or if your dog pulls away when you touch it.
5. Have a look at the skin around the ears, neck and face for itching, dandruff, hair loss or other signs of skin irritation.
6. Think about any recent changes such as a new shampoo, grooming product, food, bedding or time spent in damp conditions.
7. Check whether your dog has long, floppy or hairy ears, as these can hold warmth and moisture more easily.
8. If the smell keeps returning, make a note of when it starts and what seems to make it worse.
Common Causes
The most common reason is a build-up of wax, oil and moisture in or around the ear. That can create a cheesy or yeasty smell, especially in dogs with floppy ears or a lot of ear hair.
Yeast overgrowth is another common cause. It can happen when the ear environment becomes warm, damp or irritated, and it may go along with scratching or dark discharge.
Skin irritation, allergies or general grooming issues can also make the area smell unpleasant, even if the ear itself is not badly infected.
Less commonly, bacteria, a trapped bit of debris or another ear problem may be behind the smell. If the smell is strong, persistent or linked with discomfort, it’s best to have it checked.
What To Do
Start by checking the ears carefully in good light. If the ears only seem mildly dirty and your dog is comfortable, keep the area clean and dry and monitor whether the smell settles.
Avoid poking into the ear canal or using cotton buds, as these can make things worse or push debris further in.
If your dog has had a wet walk, a bath or a swim, gently dry the outer ear area afterwards. Keeping bedding clean and reducing dampness can also help with everyday hygiene.
Make a note of any patterns, such as the smell returning after grooming or in humid weather. That can be useful if you need to speak to a vet later.
When To Contact A Vet
Contact your vet if the smell is strong, keeps coming back, or comes with redness, swelling, discharge, pain, head shaking or lots of scratching. Ear problems can become more uncomfortable if they’re left to settle on their own.
You should also get advice sooner if your dog seems unwell, has balance problems or won’t let you near the ear.
Products That May Help
If your dog’s ears or coat tend to get a bit grimy, a gentle grooming routine can help you keep on top of everyday hygiene and notice changes early.
