Otitis externa (ear infection) is one of the most common and painful conditions in companion dogs, with floppy-eared and water-loving breeds particularly susceptible to chronic recurrence.
Dogs with chronic ear infections live with ongoing pain that is easily missed by owners who attribute ear scratching to habit rather than discomfort. The underlying cause — most often environmental or food allergies — requires management rather than repeated antibiotic courses that only treat symptoms. Dogs whose allergies are identified and managed experience dramatic reductions in ear infection frequency and the associated chronic pain. Breed selection awareness and preventive ear care after swimming or bathing also reduce welfare harm significantly.
