Dog ear infection: Why is she scratching until it bleeds? Allergies?
Ouch, poor Remington! You are correct - most ear infections in dogs stem from underlying allergies. Allergy issues in dogs mostly cause skin problems and ears are skin, after all. The allergies could be associated with environmental issues (atopy), food allergies or flea allergies. I can certainly see the discharge and swelling in Remington's ear. Her excessive scratching obviously indicates that she's quite uncomfortable. Allergy issues cause dogs to itch, which damages the skin barrier and then leads to ear infections from an overgrowth of yeast and/or bacteria in the ear canal. There are no effective over the counter treatments for ear infections. At this point, I recommend taking Remington to her vet for an exam and ear cytology. Your vet will be able to look at her ear discharge under a microscope to determine the type of infection present, and will then prescribe an appropriate medication based on those results. Until you get to the vet, consider putting an e-collar (cone) on Remington to prevent her from causing further damage to hear ears. I hope this helps and that she's feeling better soon!
