If you are noticing your pet having an odor from the ears, this may be indicative of a painful ear condition. Dogs have very long ear canals that are three times longer than the human's ear. Also, many dogs have pendulous ear flaps which in addition to the long ear canals, trap moisture and wax into the ear canals. These conditions set up a favorable environment for yeast and bacteria to grow in the ear canal and develop into a painful ear infection.
