Common Causes of Swollen Ears in Dogs
Swollen ears in dogs can be caused by a multitude of factors, each requiring different treatment approaches. Some of the most frequent causes include:
Ear Infections (Otitis Externa)
H3 What are ear infections?
Ear infections, particularly otitis externa, are a common reason for ear swelling in dogs. This condition involves inflammation of the external ear canal, the passageway between the outer ear and eardrum. It’s often caused by bacteria, yeast, or a combination of both.
H4 Symptoms of Ear Infections:
- Swelling: The ear flap may appear visibly swollen.
- Redness: The skin inside the ear canal may be red and inflamed.
- Discharge: A foul-smelling, yellow or brown discharge may be present.
- Head shaking: Your dog may excessively shake its head to try and alleviate discomfort.
- Scratching: It may scratch or paw at the affected ear.
- Pain: The dog may exhibit pain when you touch its ear.
H3 Treatment for Ear Infections:
Treatment usually involves cleaning the ear canal to remove debris and discharge, followed by topical medication. This medication may include anti-inflammatory agents, antibiotics, or anti-fungal agents depending on the underlying cause.
Allergies
H3 How do allergies cause swollen ears?
Allergic reactions in dogs can cause inflammation and swelling in the ears. These allergies can be triggered by a variety of substances, including:
- Food allergies: Some dogs develop allergies to certain ingredients in their diet.
- Environmental allergies: Allergens in the environment like pollen, dust mites, and mold can also cause ear inflammation.
- Contact allergies: Contact with certain materials like fabrics or cleaning products can cause allergic reactions.
H4 Symptoms of Allergies:
- Swelling: The ear flap may be swollen, especially with contact allergies.
- Itching: The dog may constantly scratch at its ears.
- Redness: The ear canal may appear red and irritated.
- Discharge: A clear or yellowish discharge may be present.
H3 Treatment for Allergies:
Treatment for allergies involves identifying and avoiding the allergen, if possible. This may require a thorough assessment by a veterinarian, including blood tests or allergy testing. Medications like antihistamines or corticosteroids may be prescribed to manage symptoms.
Foreign Objects
H3 Why are foreign objects a problem?
Sometimes, small objects like grass seeds, insects, or bits of debris can become lodged in the ear canal. These objects can irritate the skin and cause inflammation, leading to swelling.
H4 Symptoms of Foreign Objects:
- Swelling: The ear flap may be swollen.
- Pain: Your dog may cry out in pain when the affected ear is touched.

Tumors and Polyps
H3 Tumors and Polyps as causes of swelling:
While less common, growths like tumors or polyps inside the ear canal can cause swelling and other ear problems.
H4 Symptoms of Tumors and Polyps:
- Swelling: Persistent, often one-sided, ear swelling may indicate a tumor or polyp.
- Discharge: A bloody or foul-smelling discharge may be present.
- Hearing loss: Tumors can sometimes affect hearing.
H3 Treatment for Tumors and Polyps:
Diagnosing and treating ear tumors or polyps requires a veterinarian’s expertise. Treatment options may include surgery, radiation therapy, or medication.
Other Potential Causes:
