Chronic Ear Infections in Dogs: Causes and Veterinary Treatments

Ear infections are one of the most common reasons dogs visit the veterinarian. While occasional infections may be manageable at home, chronic or recurrent ear infections can indicate underlying health problems and cause ongoing discomfort.

Causes of Chronic Ear Infections

• Allergies: Food or environmental allergens often trigger repeated inflammation.
• Excess moisture: Swimming or frequent bathing can create a perfect environment for bacteria and yeast.
• Ear anatomy: Breeds with floppy ears or hair in the ear canal (like Cocker Spaniels or Poodles) are more prone.
• Underlying medical conditions: Hypothyroidism or autoimmune disorders can increase susceptibility.
• Parasites or foreign bodies: Ear mites, grass seeds, or debris may lead to chronic irritation.

Symptoms to Watch For

• Scratching, rubbing, or shaking the head frequently
• Redness, swelling, or discharge from the ear
• Odor coming from the ear canal
• Pain or sensitivity when touched
• Behavioral changes such as irritability or withdrawal

Veterinary Diagnosis and Treatment

Veterinarians will typically examine the ear canal, take samples for cytology, and may recommend:

• Medicated ear cleansers and topical treatments to combat bacteria and yeast
• Oral medications for severe infections or inflammation
• Addressing underlying causes such as allergies or moisture management
• Regular follow-up exams to prevent recurrence

With proper evaluation and care, most dogs recover quickly and experience fewer future infections.
