Otitis externa (ear infections) is one of the most common conditions causing discomfort in companion dogs, with chronic cases representing significant ongoing welfare harm that is preventable in many dogs.
Chronic otitis causes persistent discomfort through pain, itching, and pressure in the ear canal. Dogs with ongoing ear infections show behavioral signs including head shaking, scratching, reluctance to have ears touched, and sometimes behavioral changes from chronic pain. Many owners treat episodes as they occur without addressing underlying causes, allowing cycles of infection and temporary resolution. This pattern can continue for years with significant cumulative welfare impact. Addressing underlying allergic disease — the most common driver of recurrent otitis — provides more lasting welfare benefit than repeated antibiotic and antifungal courses. Dogs with chronic ear disease benefit enormously from dermatology referral to identify and manage the underlying cause rather than treating only the secondary infection.
