Why is My Dog Scratching Its Ears? Common Causes and How to Help

If your dog keeps scratching its ears, shaking its head, or seems uncomfortable, it’s often a sign that something’s bothering them. While an occasional scratch is normal, frequent or intense ear scratching can point to an underlying problem. Understanding what causes it can help you decide whether your pup needs a vet visit or just a little home care.

Common Reasons a Dog Scratches Its Ears

1. Ear Infections

One of the most frequent culprits behind a dog scratching its ears is an ear infection. Bacteria, yeast, or fungi can thrive in the warm, moist environment of a dog’s ear canal. Triggers include allergies, trapped water, or foreign debris. Typical signs include:

  • Red, inflamed ear tissue

  • A bad odor or visible discharge

  • Pain or swelling around the ear

2. Ear Mites

Ear mites—tiny parasites that live in the ear canal—can cause severe itching and irritation. They’re especially common in puppies and outdoor dogs. You might notice your dog scratching its ears vigorously or shaking its head constantly. These mites are contagious, so prompt veterinary treatment is essential.

3. Allergies

Dogs can develop itchy ears due to food sensitivities or environmental allergens like dust, pollen, or mold. If both ears are affected and the problem keeps coming back, allergies may be to blame. Your vet can recommend allergy testing or dietary adjustments.

4. Foreign Objects

Sometimes, grass seeds, dirt, or other small particles get trapped in a dog’s ear canal. This foreign material can cause irritation and make your dog scratch or shake its head persistently.

5. Moisture Buildup

Dogs that swim often or get frequent baths are prone to moisture-related ear problems. Excess water can lead to infection or provide the perfect breeding ground for yeast and mites. Always dry your dog’s ears thoroughly after they get wet.

Signs That Your Dog’s Ear Needs Attention

Watch for these signs if your dog is scratching its ears more than usual:

  • Frequent head shaking

  • Redness or swelling in or around the ear

  • Discharge, odor, or crusty buildup

  • Hair loss near the ears

  • Sensitivity or pain when touched

When to Call the Vet

If your dog’s ear scratching lasts longer than a few days or is accompanied by pain, odor, or discharge, it’s time to see a veterinarian. Ear infections, mites, or foreign objects require professional treatment. Ignoring the problem could lead to chronic infections or hearing loss.

How to Help a Dog Scratching Its Ears

  • Clean the ears safely: Use a vet-approved ear cleaner if your veterinarian recommends it. Avoid cotton swabs or inserting anything into the ear canal.

  • Manage allergies: Work with your vet to identify and treat food or environmental allergies.

  • Keep ears dry: Dry your dog’s ears after swimming or bathing to prevent infections.

  • Use parasite preventatives: Regular flea and mite control can reduce ear irritation.

  • Regular checkups: Routine ear inspections can help you catch problems early.

Preventing Future Ear Problems

  • Make ear cleaning part of your dog’s grooming routine.

  • Limit exposure to allergens when possible.

  • Keep your dog’s bedding and play areas clean.

  • Schedule yearly vet visits for ear and overall health checks.
