Otitis Externa

Otitis externa refers to inflammation or infection affecting the outermost part of the ear canal, from the visible ear flap (pinna) down to the eardrum. This common condition can be caused by various factors, including allergies, ear mites, bacteria, yeast, foreign bodies, excessive moisture, or even underlying systemic diseases. Pets with otitis externa often show signs of discomfort, such as head shaking, pawing at the ear, or rubbing their head. The affected ear may appear red, swollen, and produce a discharge that can range from waxy to pus-like, often accompanied by an unpleasant odor. Prompt veterinary diagnosis is crucial to identify the underlying cause and prescribe appropriate treatment, which may include ear cleaning, topical medications, and sometimes oral antibiotics or anti-inflammatories. Untreated cases can lead to chronic issues or deeper ear infections.
