Ears are very sensitive organs. Breeds with long ears are prone to ear disease more than breeds with pricked ears. Moreover, various diseases of the ear are more common in breeds with richly haired ears.
Infection of the ear canal can be suspected when the dog shakes his head very often, persistently and repeatedly scratches his ears, holds his head to one side, wipes his ears on the pad or when dark, smelly or purulent discharge from the ear canal can be detected.
Infections of the ear canal can result in hearing loss. Other causes of deafness may be congenital defects (described e.g. in dalmatians) and, of course, the age of the organism.
Infections of the ear canal and deafness caused by infections can be prevented by gentle cleaning of the external ear and the inner wall of the ears. The removal of impurities can be done with a cleaning swab soaked in a product containing mineral oils or a veterinary product in the form of aqueous solutions containing active substances(e.g. camomile extract). In some breeds (eg. a poodle) it is desirable to pull out or pluck hair out of the ear canal area.
In the case that an active infection of the ear canal or hearing impairmnet is suspected. Also, if you are not familiar with how to cut out (pluck) the ear canal, consult it with your vet.
