What are ear mites?

Ear mites are tiny parasites that live in the ear canal of dogs (and cats). The most common sign of ear mite infection is scratching of the ears. Sometimes the ears will appear dirty because of a black material in the ear canal; this material is sometimes shaken out. The instrument we use for examining the ear canals, an otoscope, has the necessary magnification to allow us to see the mites. Sometimes, we can find the mites by taking a small amount of the black material from the ear canal and examining it with a microscope. Although they may leave the ear canals for short periods of time, they spend the vast majority of their lives within the protection of the ear canal. Transmission generally requires direct ear-to-ear contact. Ear mites are common in litters of puppies if their mother has ear mites.

Ear infections may also cause the production of a dark discharge in the ear canals. It is important that we examine your puppy to be sure the black material is due to ear mites and not infection. Please do not ask us to just dispense medication without having the opportunity to make an accurate diagnosis.
