Cookie, a spirited three-year-old Labrador retriever, was the picture of health—except for her ears. Repeated bouts of otitis externa (OE) plagued and frustrated her and her owner. Despite multiple treatments, the infections returned. A thorough workup revealed canine adverse food reaction (CAFR) as the primary cause. By implementing a prescription hydrolyzed protein elimination diet, Cookie's OE was controlled, and relapses were prevented. Her owner was taught how to perform individual ingredient challenges and address flares. Her case exemplifies how addressing underlying causes can transform the prognosis for pets suffering from OE.
Otitis externa is inflammation of the ear canal, often accompanied by secondary bacterial or yeast infections. It is a common reason for pet owners to seek veterinary care. Although infections may resolve with treatment, recurrences are frequent if underlying causes are not addressed. Over time, inflammation can cause chronic, irreversible changes, making management increasingly difficult.
