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

If your dog is constantly scratching its ears, it can be distressing for both of you. Ear scratching might be a sign of underlying health issues that need attention. Understanding the common causes can help you identify whether your dog needs veterinary care or simple home treatment. Read on to learn why your dog might be scratching its ears and what steps to take.

Common Causes of Dog Ear Scratching

Ear Infections

Bacterial, yeast, or fungal infections are among the most common causes of ear scratching in dogs. These infections often result from moisture, allergies, or irritants trapped in the ear canal. Symptoms include redness, discharge, foul odor, and swelling.

Ear Mites

Tiny parasites like Otodectes cynotis (ear mites) can cause intense itching, especially in puppies and outdoor dogs. Mites are highly contagious and require veterinary treatment.

Allergies

Environmental allergens (pollen, dust, mold) or food allergies can cause inflammation in the ears, leading to itching and discomfort. Allergic reactions often affect both ears and can be recurrent.

Foreign Bodies

Debris, grass seeds, or small objects can get lodged in the ear canal, causing irritation and constant scratching or head shaking.

Excess Moisture

Moisture from swimming, baths, or high humidity can create an environment conducive to infections or mite infestations.

Signs to Watch For

  • Frequent head shaking
  • Redness or swelling in the ear canal
  • Discharge or foul odor
  • Scratching or pawing at the ears
  • Hair loss around the ears
  • Pain or sensitivity when touching the ears

When to See a Veterinarian for Dog Ear Scratching

If your dog’s ear scratching persists for more than a couple of days or is accompanied by other symptoms like discharge, odor, or pain, consult your veterinarian. Ear infections or mites require proper diagnosis and treatment to prevent long-term damage.
