Quick answer
That cheesy smell coming from your Frenchie's ears? It's likely a yeast infection.
INFO: Frenchie ears are open and easy to inspect: that means you can catch wax, odor, and early inflammation before a full infection sets in.
Signs of Ear Yeast Infection
Brown waxy discharge, smell, and constant head shaking are key symptoms.
The ear findings that matter most
- Odor, discharge color, and whether the wax looks dry, greasy, or excessive.
- Head shaking, scratching, ear rubbing, or sensitivity when the flap is touched.
- Redness deep in the canal versus mild debris only in the outer ear.
- Whether allergies, swimming, or recent bathing seem to trigger flare-ups.
Safe ear cleaning basics
A good ear-cleaning routine loosens debris and dries the canal without pushing material deeper.
- Use a vet-approved ear cleaner and fill the canal gently as directed on the label.
- Massage the base of the ear, let your dog shake, then wipe away loosened debris from the outer canal.
- Never put cotton swabs deep into the ear canal.
- Stop cleaning and book a visit if the ear looks painful, very red, or full of discharge.
When to call your vet
Yeast, bacteria, mites, and allergies can all create similar early symptoms, which is why repeat ear problems are best handled with actual examination and cytology instead of guessing.
- Pain, crying, or a tilted head.
- Strong odor with thick brown, yellow, or bloody discharge.
- Swelling that narrows the ear canal or prevents cleaning.
- Loss of balance, repeated infections, or no improvement after basic cleaning.
How to reduce repeat flare-ups
- Dry ears after baths or swimming.
- Clean on a routine that matches your dog's wax and allergy pattern, not randomly.
- Treat skin allergies because the ears are often part of the same inflammatory picture.
- Recheck chronic ear issues before scar tissue makes them harder to manage.
Final Thoughts
Yeast ear infections are itchy, smelly, and stubborn in Frenchies with their narrow canals and skin folds. Drying the ears, using vet-prescribed drops, and addressing the underlying allergy that feeds the yeast are all necessary for long-term relief. Treating only the ears while ignoring the allergy guarantees the infection will return.
Yeast loves moisture.
Dryness is your weapon.
