Infections of the external ear canal (outer ear) by bacteria or yeast, are one of the most common types of infections seen in dogs. Some breeds, such as Cocker Spaniels and Poodles, seem more prone to ear infections but they may occur in any breed. A dog with an ear infection is uncomfortable; his ear canals are sensitive. Ear mites can cause several of these symptoms, including a black discharge, scratching, and head shaking. There are several kinds of bacteria and at least one type of fungus which might cause an ear infection. First, the ear canal is examined with an otoscope, an instrument that provides magnification and light. The next step is to examine a sample of the material from the ear canal to determine which organism is causing the infection. The results of the otoscopic examination and cytology tell the veterinarian what to do. Cytologic study of debris from the ear canal dictates which drug to use.
