Otitis externa (outer ear infection) is one of the most common veterinary conditions in dogs, causing chronic pain and discomfort that is frequently undertreated. Understanding its welfare implications improves owner response.
Ear infections cause persistent pain that significantly affects dogs' quality of life, yet they are often undertreated because owners normalize the scratching and head-shaking as behavioral quirks. An actively infected ear causes constant burning and itching - dogs with ear infections sleep poorly, scratch to the point of self-injury, and show behavioral changes including grumpiness, withdrawal, and head-shaking. The otic epithelium is richly innervated, making ear infections genuinely painful. Chronic otitis, if poorly managed, progresses to middle ear involvement and potentially permanent hearing loss or balance disorders. The treatable nature of most ear infections makes the chronic suffering of poorly managed cases a particularly avoidable welfare outcome.
