Overview
Otitis externa (outer ear infection) is the most common ear problem in dogs, caused by bacteria, yeast, or both — often triggered by allergies, moisture, or anatomical factors like floppy ears. Cats get ear infections less frequently but can develop them from mites, polyps, or allergies. Left untreated, outer ear infections can progress deeper, causing permanent hearing damage.
Symptoms to Watch For
- Head shaking and ear scratching
- Red, swollen ear canals
- Dark brown or yellow discharge
- Foul odor from the ears
- Tilting head to one side
How Nutrition Helps
Most chronic ear infections are secondary to underlying allergies — food allergies account for a significant percentage. Omega-3 fatty acids reduce allergic inflammation that predisposes to infections. Addressing food allergies through elimination diets can resolve recurring ear infections completely. Zinc supports immune defense against yeast and bacteria.
How Activity Helps
Dry ears thoroughly after swimming or bathing. Keep water out of ear canals during water activities.
Prevention Tips
- Clean ears regularly with vet-approved ear cleaner
- Dry ears thoroughly after swimming or bathing
- Address underlying food allergies
- Don't use cotton swabs deep in the ear canal
- Check ears weekly for redness, odor, or discharge
Breeds at Higher Risk
Cocker Spaniels, Basset Hounds, Labrador Retrievers, Golden Retrievers, Shar Peis, and Poodles. Any breed with floppy ears or hairy ear canals.
