Ear infections in dogs are a common yet serious health concern. If left untreated, they can cause significant discomfort, lead to chronic issues, and even affect your dog’s hearing. Certain breeds, environmental factors, and underlying health conditions can increase the risk of infection.

At Town & Country Animal Hospital in Athens, Alabama, we understand that pet owners want to ensure their dogs remain happy and healthy. This guide will help you identify the signs of an ear infection, understand its causes, and explore effective treatment and prevention strategies.

Causes of Ear Infections in Dogs

Canine Ear Anatomy and Why It Matters

A dog’s ear canal is shaped differently from a human’s—it is L-shaped and deeper, making it easier for moisture, debris, and wax to become trapped. This creates an ideal environment for bacteria and yeast to thrive, leading to infections.

Dogs that frequently swim, bathe, or live in humid climates (such as in Athens, Alabama) are at higher risk because their ears stay damp longer, allowing bacteria and fungi to multiply.

Common Triggers of Ear Infections

Several factors contribute to ear infections in dogs, including:

  • Bacterial and Yeast Overgrowth – Naturally occurring microorganisms can become overabundant and cause infections.
  • Ear Mites – Common in puppies and outdoor dogs, ear mites cause intense itching and inflammation.
  • Allergies – Environmental and food allergies can lead to chronic ear infections. Dogs with allergies often suffer from inflamed skin, excessive ear wax production, and secondary bacterial or yeast infections. Learn more about dog allergies and treatment.
  • Foreign Objects – Grass seeds, dirt, or debris trapped in the ear canal can cause irritation and infection.
  • Excessive Wax Buildup – Some dogs naturally produce more wax, which can trap bacteria and moisture.

Signs Your Dog May Have an Ear Infection

Recognizing the early signs of an ear infection can help prevent long-term complications. Be on the lookout for:

  • Frequent head shaking or ear scratching
  • Redness and swelling inside the ear
  • Foul odor coming from the ear
  • Dark or yellow discharge
  • Whining or yelping when the ears are touched
  • Tilting the head to one side or difficulty balancing

In more severe cases, dogs may develop ear hematomas, where blood vessels in the ear flap rupture due to excessive scratching or head shaking. Learn more about ear hematomas in dogs.

If your dog is showing any of these symptoms, schedule a veterinary visit as soon as possible.

Diagnosing Ear Infections in Dogs

What to Expect at the Vet

At Town & Country Animal Hospital, we use advanced techniques to accurately diagnose ear infections:

  1. Otoscope Exam – A specialized tool allows veterinarians to examine deep inside the ear canal for blockages, infections, or mites.
  2. Ear Swab Cytology – A sample of ear discharge is examined under a microscope to identify bacteria, yeast, or mites.
  3. Allergy Testing – If infections are chronic, allergy testing may be recommended to identify underlying causes.

Effective Treatments for Ear Infections

Medications and Veterinary Interventions

Once an infection is diagnosed, treatment typically includes:

  • Prescription Ear Drops – Medications containing antibiotics, antifungals, or steroids to reduce inflammation and fight infection.
  • Oral Medications – For severe infections, oral antibiotics or antifungal medications may be required.
  • Ear Cleaning Procedures – In cases of severe wax buildup or debris, a veterinarian may perform a deep ear cleaning under sedation.

At-Home Care and Follow-Up

  • Administer all prescribed medications exactly as directed to prevent recurrence.
  • Keep your dog’s ears dry after baths and swimming—use a clean, dry towel to remove excess moisture.
  • Monitor for signs of recurrence and schedule follow-up visits as needed.

Preventing Ear Infections in Dogs

Routine Ear Care

Preventive care is key to reducing the risk of recurrent infections. Follow these steps:

  • Regular Ear Cleaning – Clean your dog’s ears weekly or biweekly with a vet-approved solution. Avoid over-cleaning, as this can strip away natural protective oils.
  • Dry Ears After Water Exposure – Use a cotton ball or clean towel to remove moisture after swimming or bathing.
  • Address Underlying Allergies – Dogs prone to allergies often experience recurring ear infections. Proper allergy management can significantly reduce flare-ups. Read more about pet allergy management at Purdue Veterinary Hospital.

Professional Grooming & Ear Checks

For long-haired or floppy-eared breeds, regular grooming is essential. Trimming hair around the ears improves airflow and reduces moisture buildup. Learn more about the benefits of regular pet grooming.

When to Visit Town & Country Animal Hospital

Ear infections won’t go away on their own and often worsen without proper treatment. If your dog shows persistent symptoms, frequent infections, or severe discomfort, it’s time to schedule a veterinary exam.
