Ear infections are one of the most common reasons dogs visit the veterinarian. In Fountain Hills, Arizona, environmental factors like dust, pollen, and grass awns (foxtails) can increase the risk of chronic ear infections. At Palisades Veterinary Hospital, we are dedicated to helping pet owners understand how to prevent, recognize, and treat these uncomfortable and sometimes serious infections.

This guide will provide an in-depth look at why dogs develop ear infections, the best prevention strategies, treatment options, and when to seek veterinary care.

Why Do Dogs Get Ear Infections?

Unlike human ear canals, a dog’s ear canal is vertical and L-shaped, making it more prone to moisture retention and debris buildup—a perfect environment for bacteria and yeast to thrive. Several underlying factors contribute to ear infections:

1. Bacterial and Yeast Overgrowth

  • Ear infections are often caused by bacteria, yeast, or a combination of both.
  • Dogs that swim frequently or have floppy ears (e.g., Golden Retrievers, Basset Hounds, and Cocker Spaniels) are more susceptible.
  • Moisture trapped in the ear creates the perfect breeding ground for infections.

2. Allergies: A Leading Cause

  • Food and environmental allergies trigger inflammation in the ear canals, leading to chronic infections.
  • Allergies can also cause excess wax production, worsening the problem.
  • Learn more about how allergies contribute to ear infections from Dog Allergies: Symptoms & Treatment – AKC.

3. Foreign Bodies: The Danger of Foxtails

4. Hormonal Disorders

  • Hypothyroidism and other endocrine disorders can weaken the skin barrier, leading to chronic infections.

Signs of an Ear Infection in Dogs

Early detection prevents more severe complications. Watch for:

  • Frequent head shaking or ear scratching
  • Redness, swelling, or warmth in the ear
  • Foul odor coming from the ear
  • Brown, yellow, or black discharge
  • Pain when the ear is touched
  • Hearing loss or loss of balance

If left untreated, infections can progress into middle and inner ear infections, potentially leading to hearing loss and neurological symptoms.

 Ear Hematomas (Cauliflower Ear)

Chronic ear infections lead to excessive scratching and head shaking, which can rupture blood vessels in the ear flap, causing painful hematomas.Hematomas often require surgical correction– Learn more about this condition from Ear Hematoma in Dogs – AKC.

Preventing Ear Infections: A Proactive Approach

1. Regular Ear Cleaning: The First Line of Defense

Cleaning your dog’s ears helps remove wax, dirt, and allergens, reducing infection risks.

Best Practices for Ear Cleaning:

  • Use a vet-approved ear cleaner to break down wax.
  • Gently wipe the ear with a soft cotton pad (never use Q-tips!).
  • Avoid over-cleaning, which can strip natural defenses.

2. Dry Your Dog’s Ears After Swimming or Bathing

  • Use a clean, dry towel to remove moisture after water exposure.
  • Consider using a vet-approved drying solution for dogs prone to infections.

3. Maintain a Healthy Diet for Stronger Skin and Immune Health

  • A balanced diet rich in omega-3 fatty acids promotes healthy skin and ears.
  • Dogs with allergy-related ear infections may benefit from hypoallergenic diets.

4. Keep Hair Trimmed Around the Ears

  • Dogs with excessive hair in the ear canal (e.g., Poodles, Shih Tzus) may need professional grooming.
  • Regular grooming prevents debris buildup and improves air circulation.
  • Read more about why grooming matters from Regular Pet Grooming – ASPCA.

5. Routine Veterinary Check-Ups

  • Regular ear exams can detect early signs of infection.
  • Customized care plans help prevent recurrences.

Diagnosing & Treating Ear Infections

How Our Veterinarians Diagnose Ear Infections

At Palisades Veterinary Hospital, we use a comprehensive diagnostic approach:

  • Otoscope Exam – Visual inspection of the ear canal for inflammation or foreign objects.
  • Ear Cytology – Microscopic evaluation to determine if bacteria, yeast, or mites are present.
  • Culture & Sensitivity Testing – Identifies the exact cause and best treatment plan.

Treatment Options

Once diagnosed, treatment may include:

  1. Topical Medications – Antibiotic, antifungal, or steroid ear drops.
  2. Oral Medications – Used for severe or recurring infections.
  3. Deep Ear Cleaning – Performed under sedation for chronic cases.
  4. Surgical Intervention – For severe or resistant infections to prevent long-term damage.

FAQs About Ear Infections in Dogs
