How to treat a dog ear infection at home?

Dog shaking its head nonstop or scratching at its ears might be more than just a nuisance—it could signal an ear infection. While severe cases need a vet’s care, mild infections often respond well to at-home treatments, as long as you know what to do (and what to avoid).​

First, spot the signs. Redness inside the ear, a foul odor, or a waxy discharge (brown, yellow, or even bloody) are telltale clues. A beagle in Denver started rubbing her ear against furniture; her owner checked and found a small amount of dark wax—early signs that prompted quick action.​

Before treating, gently clean the ear to remove debris. Mix equal parts warm water and white vinegar (or use a vet-recommended ear cleaner) on a cotton ball—never a Q-tip, which can push gunk deeper or damage the eardrum. Wipe the outer ear canal softly, stopping if your dog pulls away or yelps.​

For mild bacterial or yeast infections, over-the-counter ear drops with ingredients like hydrocortisone can reduce inflammation and itching. Follow the package directions, usually putting a few drops in each ear twice a day. A schnauzer in Portland improved after three days of this routine, but his owner stopped immediately when he still seemed painful on day four.​

Avoid home remedies that can harm. Hydrogen peroxide irritates sensitive ear tissue, and olive oil can trap moisture, making infections worse. Some people swear by garlic oil, but it’s toxic to dogs—always stick to products labeled safe for canine use.​

Keep ears dry, especially after baths or swims. Breeds with floppy ears (like cocker spaniels) or heavy ear hair (poodles) are more prone to infections because air doesn’t circulate well. A quick dry with a towel or a hair dryer on the lowest, coolest setting can prevent moisture buildup.​

Know when to call the vet. If your dog has a fever, won’t eat, or the ear is swollen shut, it’s time for professional help. In many areas, neglecting a pet’s medical needs can violate animal welfare laws—cities like Chicago and Miami have strict regulations about providing timely veterinary care.​

Prevent future infections by checking ears weekly. A quick look during grooming sessions can catch early signs before they worsen. Dogs that love water might need more frequent checks; consider ear drying solutions designed for post-swim use, available at pet supply stores.​

At-home treatment works for mild cases, but never delay a vet visit if things don’t improve. Your dog’s comfort—and health—depend on knowing the difference between what you can handle and when to get expert help. With care, most ear infections clear up quickly, letting your pup get back to wagging instead of scratching.
