What are the differences between dirty ears and ear mites in pets, and how can they be distinguished from each other?

Dirty ears in pets are typically caused by a buildup of wax and debris, while ear mites are tiny parasites that infest the ear canal. Dirty ears may have a strong odor and visible dirt or wax, while ear mites can cause itching, redness, and dark discharge resembling coffee grounds. A veterinarian can perform a microscopic examination to confirm the presence of ear mites. Regular cleaning and maintenance can help prevent both dirty ears and ear mites in pets.
