What is the best practice when cleaning a dog's ears if there is a history of infections?

• A. Clean the entire ear canal using a standard ear cleaner and flush thoroughly.
• B. Use cotton swabs deep into the canal to remove debris.
• C. Clean the outer ear only as advised, avoid deep canal clean, and refer to a veterinarian if infection signs appear or if you are unsure.
• D. Skip cleaning and just dry the ear with a towel.

Answer: (C)

In dogs with a history of ear infections, the priority is to maintain cleanliness while avoiding anything that could worsen the problem. Deep cleaning or flushing the entire ear canal can irritate inflamed tissue, potentially damage delicate structures inside, and may push debris deeper, making infection harder to treat. Cotton swabs should not be inserted into the canal, as they can cause trauma or pack debris further into the ear.

The best practice is to clean only the outer ear as advised, using gentle, veterinarian-approved techniques, and to refer to a veterinarian if infection signs appear or if you’re unsure. If infection is present, a vet may prescribe medicated cleaners or treatments and may need to perform a professional cleaning under supervision. Signs that warrant veterinary evaluation include redness, swelling, discharge, a foul odor, or persistent scratching and head shaking.

Other options either risk causing harm (deep cleaning into the canal, especially with swabs) or neglect essential care (skipping cleaning entirely or trying to clean deeply without guidance).
