Ear infections are one of the most common conditions we treat in dogs and they can cause significant discomfort if not identified and managed early. At Stanton Pet Hospital, our team is here to help pet owners understand the causes, symptoms, and treatment options for ear infections, along with the best ways to prevent them from recurring.

What Causes Ear Infections in Dogs?

Most canine ear infections result from a combination of anatomy, environment, and underlying health conditions. A dog’s ear canal is L-shaped, which makes it prone to trapping moisture and debris, creating the perfect environment for bacteria, yeast, or even parasites to thrive.

The Role of Allergies

Allergies are a major contributor to recurring ear infections. Dogs with:

  • Environmental allergies (pollen, mold, dust mites)
  • Food allergies or sensitivities (proteins, grains)

often experience inflammation in the ear canal that disrupts the normal balance of bacteria and yeast. Over time, this inflammation can weaken the ear’s natural defenses, leading to infection.

Breed-Specific Risks

Some breeds are more likely to develop ear infections due to their ear structure or predisposition to skin conditions:

  • Floppy-eared breeds (e.g., Cocker Spaniels, Basset Hounds) tend to trap moisture more easily
  • Breeds with hairy or narrow ear canals (e.g., Poodles, Shar-Peis) may experience reduced airflow
  • Retrievers and active outdoor dogs are more prone to swimmer’s ear and debris-related infections

Routine grooming and frequent ear checks are especially important for these pets.

Symptoms of Ear Infections in Dogs

Recognizing the early signs of an ear infection can help prevent more serious complications. Common symptoms include:

  • Persistent head shaking or ear scratching
  • Foul odor from one or both ears
  • Discharge (yellow, brown, black, or bloody)
  • Redness, swelling, or sensitivity inside the ear
  • Tilting the head or loss of balance

Keep in mind: these signs can also indicate other issues, such as ear mites, foreign bodies (like foxtails), or even ear tumors (Tumors of the Ear Canal)—making a proper veterinary exam essential.

Diagnosing Ear Infections at Stanton Pet Hospital

At Stanton Pet Hospital, we use a comprehensive approach to accurately diagnose the type and cause of your dog’s ear infection.

Initial Examination

Advanced Diagnostics (If Needed)

In rare or advanced cases, your veterinarian may discuss surgical options such as Total Ear Canal Ablation (TECA).

Treatment Options for Canine Ear Infections

Treatment depends on the type of infection, severity, and underlying cause.

Medical Therapy

  • Topical ear medications (antibacterial, antifungal, anti-inflammatory)
  • Oral antibiotics or antifungals for deeper or chronic infections
  • Ear flushes under sedation if the ear is too painful to clean awake

We’ll demonstrate proper medication techniques and provide follow-up care to ensure healing is on track. Here’s a guide on safe ear cleaning from Cornell University.

Preventing Ear Infections: Practical Tips for Pet Owners

1. Regular Ear Cleaning

Use only veterinarian-recommended ear cleaners—never alcohol, hydrogen peroxide, or cotton swabs. A simple routine:

  1. Fill the canal with solution
  2. Massage the base of the ear
  3. Let your dog shake
  4. Wipe the outer ear with gauze or soft cloth

Avoid over-cleaning, which can cause irritation. We’ll help you set the right schedule.

2. Nutrition and Allergies

Diet plays a major role in managing inflammation and allergic responses. In some dogs, switching to a hypoallergenic or limited-ingredient diet can dramatically reduce symptoms.

3. Post-Bath & Post-Swim Care

Always dry your dog’s ears thoroughly after water exposure. Dogs prone to swimmer’s ear may benefit from drying solutions after every swim.

FAQs: Ear Infections in Dogs

What if I see discharge in my dog’s ear?

Discharge is a clear sign of infection. Don’t wait—delaying treatment can lead to pain, chronic infection, or even complications like ear hematomas.

How often should I clean my dog’s ears?

It depends on breed, lifestyle, and history. Some dogs need weekly cleaning; others only monthly. We’ll personalize a plan for you.

When is an ear infection an emergency?

Seek immediate care if your dog shows:

  • Severe pain
  • Inability to walk or stand
  • Rapid ear swelling
  • Continuous head tilting or disorientation

These symptoms may indicate a deep or middle ear infection, which can affect balance and coordination.
