Overview of Osurnia Medication for Dogs
- Osurnia is a medication to treat ear infections in dogs. Otitis externa (outer ear infections) commonly include infection with both bacteria and yeast organisms.

You can learn more about otitis externa in these articles from the site library: Otitis Externa (Ear Infections) in Dogs and Otitis Externa (Ear Infections) in Cats.
