Dog Ear Infection Symptoms and Home Care
The classic signs are head shaking, scratching at the ear, a sour smell, and red or waxy canals. Most infections need prescription drops, not just cleaning.

Symptoms to spot

- A strong, yeasty odor.
Why ears get infected
Floppy ears, moisture after swimming, and allergies are the big drivers. Yeast and bacteria both cause it, which is why the treatment differs.
Do not pour oil, vinegar, or alcohol into the ear — and never if your dog is in pain or the eardrum may be damaged. A vet confirms the type and gives the right drops.
Cleaning at home
Use only a vet-approved ear cleaner: fill the canal, massage the base, let the dog shake, then wipe the outer ear. Never push cotton swabs deep.
Preventing repeat infections
Dry ears after baths and swimming, manage underlying allergies, and clean on a schedule your vet recommends rather than when it already smells.
Frequently asked questions
Can I treat a dog ear infection at home?
Mild cases need vet-prescribed drops after confirming yeast vs bacteria. Home cleaning alone rarely clears an established infection.
What does an infected dog ear smell like?
A sour, yeasty, or musty odor is the tell-tale sign, usually with wax and redness.
How do I clean my dog's ears safely?
Use a vet-approved cleaner, fill and massage the canal, let them shake, wipe the outside. Never insert swabs deep into the ear.
