Understanding Ear Infections in Dogs: A Comprehensive Guide
Recognizing Ear Infections in Dogs
Ear infections are a common concern for dog owners and can cause significant discomfort for pets. If left untreated, they may lead to chronic pain, hearing loss, or recurring infections. Early recognition and treatment are key to maintaining your dog’s ear health and overall well-being.
Causes of Ear Infections in Dogs
A dog’s unique ear structure, especially in breeds with long or floppy ears, makes them more prone to infections. Common causes include:
- Bacteria and yeast overgrowth – Warm, moist environments inside the ear canal encourage microbial growth.
- Allergies – Food and environmental allergies can cause chronic ear inflammation.
- Foreign objects – Grass seeds, dirt, or debris can become trapped in the ear canal, leading to irritation and infection.
- Ear mites – These tiny parasites cause intense itching and inflammation, especially in puppies.
- Excess moisture – Dogs who swim frequently or are bathed often are more prone to infections due to trapped water.

Symptoms of Ear Infections
If your dog has an ear infection, you may notice:
- Persistent head shaking or tilting
- Scratching at the ears
- Redness, swelling, or warmth around the ear
- Foul odor coming from the ears
- Yellow, brown, or bloody discharge
- Sensitivity when touching the ears
In severe cases, dogs may experience loss of balance, walking in circles, or hearing difficulties, which can indicate an infection that has spread to the inner ear.
Preventing Ear Infections
Routine Ear Cleaning
Keeping your dog’s ears clean is one of the most effective ways to prevent infections. Regular ear cleaning helps remove wax, debris, and excess moisture that can contribute to bacterial and yeast growth.
- Use a vet-recommended ear cleaner and a cotton ball (never cotton swabs).
- Clean your dog’s ears after swimming or bathing to prevent moisture buildup.
- Check for signs of redness, swelling, or an unusual smell during routine care.

Managing Allergies
Dogs with allergies are more prone to ear infections due to chronic inflammation. If your dog experiences itchy skin, ear infections, or excessive licking, an allergy test may help determine the cause. Treatment options include:
- Switching to a hypoallergenic diet
- Using antihistamines or allergy medications
- Minimizing exposure to allergens, such as dust or pollen

Diagnosing Ear Infections
If you suspect your dog has an ear infection, a veterinarian will conduct a thorough examination, which may include:
- Otoscope examination – To inspect the ear canal and eardrum.
- Ear swab and cytology – To identify bacteria, yeast, or mites under a microscope.
- Allergy testing – If chronic infections are suspected to be allergy-related.
A proper diagnosis ensures that the most effective treatment plan is used to resolve the infection.
Treatment Options for Ear Infections
Medications
- Topical ear drops – Contain antibiotics, antifungals, or anti-inflammatory ingredients.
- Oral antibiotics or steroids – May be necessary for severe infections.
- Ear flush or deep cleaning – In cases of excessive wax or debris buildup.

Surgical Intervention
In severe or chronic cases, surgery may be required to remove damaged tissue or improve airflow in the ear canal. A Total Ear Canal Ablation (TECA) may be performed in cases of extreme infection or recurring issues.
Managing Chronic and Recurring Ear Infections
If your dog suffers from frequent ear infections, long-term management may be needed. Your veterinarian may recommend:
- Regular ear cleanings to prevent buildup.
- Prescription diets to reduce allergy-related inflammation.
- Allergy medications or immunotherapy.
Ear Hematomas
Frequent ear infections or excessive head shaking can lead to ear hematomas, which occur when blood vessels rupture inside the ear flap. If left untreated, they can cause permanent scarring or ear deformity.

When to Seek Veterinary Care
Seek professional care if your dog:
- Shows persistent symptoms despite at-home cleaning
- Has severe pain or swelling in the ear
- Develops a strong odor or unusual discharge
- Has trouble walking, balancing, or hearing
