Otitis Externa in Dogs and Cats: Smelly Ears, Infections, and Chronic Cases

Otitis externa means inflammation of the external ear canal—often itchy, painful, and odorous. Underlying allergy is common in recurrent cases.

Presentation

Head shaking, scratching ears, erythema, discharge, malodor.

Otitis media risk

Chronic or untreated infection can extend inward—only veterinarians should diagnose middle ear involvement.

Pet NGON grooming includes routine outer-ear observation during bathing but does not replace cytology or prescriptions.


Sanitary trims around ears and professional drying after baths reduce moisture retention once treatment allows grooming.

Next step: Vet cytology for smelly ears; Pet NGON bathing after clearance using vet-approved ear handling only.
