Dog ear infections are frustrating, smelly, and painful—and often keep coming back. This episode is part of the HEAR NOW series (Help, Educate, Assess, Regulate), created in partnership with Merck Animal Health. In this two-part series, expert guest Dr. Christine McKinney, Merck Animal Health Small Animal Dermatology Specialist, joins to answer the most frequently asked questions about dog ear infections to give pet owners the clear, evidence-based information they need. 

In Part 2 of our HEAR NOW series, we explain what brown discharge really means, why infections may not go away, the risks of untreated infections, and why home remedies can do more harm than good. Learn safe, effective treatments to help your pet.

• Brown discharge can be normal wax, yeast, or bacteria—cytology is the only way to know.

• Infections that don’t clear may need longer treatment, stronger antiinflammatory medications, or better control of the primary disease like allergies.

• Inflammation drives infection—managing allergies reduces recurrence.

• Untreated infections can spread to the middle or inner ear, causing permanent damage.

• Home remedies like vinegar may burn inflamed ears and risk hearing loss.
