Otitis externa

Definition
Otitis externa is the inflammation of the external ear canal. It is a common problem that affect 14-20% of dogs.

Clinical signs of canine otitis externa
Pruritis (itching) of the ear
Head shaking
Exudate (discharge) present in and around the external ear canal
Malodor (bad smell) from the ear

Why dogs get otitis externa
Most dogs get otitis externa because of allergies to environmental substances. The allergic reaction makes the ear itchy. Dogs respond by scratching, which damages the lining of the ear canal. Yeast and bacteria then seize the opportunity and infect the skin.
