If your dog is constantly scratching at their ears, shaking their head, or suffering from foul-smelling discharge—you’re not alone. Chronic ear infections are one of the most frustrating and emotionally draining issues dog owners face. At Oliver Animal Hospital in Austin, Texas, we see it all the time: the same dogs coming in month after month with painful, inflamed ears, and their owners worn out from the cycle of treatment, recurrence, and worry.

It’s not just heartbreaking—it’s also expensive, time-consuming, and, let’s be honest, kind of gross. The smell, the discharge, the endless vet visits. So why does it keep happening? And more importantly, how do you get to the bottom of it?

This guide covers:

  • Common signs of ear infections
  • What causes recurring ear problems
  • Treatment options that actually work
  • Preventive steps to break the cycle

Recognizing the Signs of an Ear Infection in Dogs

Dogs can’t tell you they’re in pain, but their behavior often speaks volumes. Look for:

  • Persistent head shaking or scratching at the ears
  • Redness, swelling, or warmth around the ears
  • A strong, foul odor (you know the one)
  • Waxy, brown, or yellow discharge
  • Whining or flinching when ears are touched
  • Loss of balance or coordination in severe cases

Why Does My Dog Keep Getting Ear Infections?

1. Breed and Anatomy

Some breeds are simply more prone to ear infections:

  • Floppy-eared dogs (like Labradors, Cocker Spaniels, and Basset Hounds) trap moisture and lack airflow.
  • Hairy-eared breeds (like Poodles and Schnauzers) accumulate debris deep in the canal.

Their anatomy creates the perfect storm for infection.

2. Allergies: The Silent Culprit

Many recurring ear infections have an underlying cause—allergies. Whether it’s environmental (pollen, mold) or food-related, allergies inflame the skin and disrupt the normal ear environment.

Look for signs like:

  • Itchy paws or skin
  • Redness, especially around the face and ears
  • Frequent ear infections, often in both ears

3. Bacteria, Yeast, and Mites

A healthy ear keeps these microbes in balance. But once inflammation starts, the ecosystem goes haywire:

  • Yeast loves warm, moist environments
  • Bacteria thrive in damaged skin
  • Ear mites (especially in puppies) can cause intense irritation and debris

4. Moisture and Poor Hygiene

Water from baths or swimming can sit in the ears and feed yeast and bacteria. Using harsh cleaners or cotton swabs can also damage the ear canal.

How We Treat Dog Ear Infections (And Help Them Stay Gone)

When to Call the Vet

Don’t wait for it to “clear up on its own.” If you notice foul odor, redness, swelling, or your dog is constantly scratching, it’s time for a vet visit.

Diagnostic Testing

We start by identifying what we’re up against:

  • Ear cytology to check for yeast, bacteria, or mites
  • Culture & sensitivity for resistant infections
  • Allergy testing if the infections are chronic or seasonal

Treatment Options

Based on the findings, we may recommend:

  • Prescription ear drops with antibiotics or antifungals
  • Steroids to reduce inflammation
  • Medicated ear flushes
  • Ear hematoma treatment, if the ear has been damaged from shaking. Learn more at Ear Hematoma in Dogs

Severe cases might require sedation for deep ear cleaning and ear canal flushing.

How to Prevent Recurring Ear Infections

Clean Ears—But Do It Right

  • Use a vet-approved ear cleaner
  • Avoid cotton swabs deep in the ear canal
  • Clean after baths or swimming

Step-by-step instructions: How to Clean Your Dog’s Ears

Keep Ears Dry

Always dry your dog’s ears thoroughly after swimming or bathing. Consider a drying solution recommended by your vet.

Manage Allergies

Allergy control is often key to long-term ear health:

  • Elimination diets
  • Allergy medications
  • Regular ear checks

Check for Foreign Bodies Like Foxtails

Especially in outdoor dogs, foxtails can lodge in the ear and cause serious damage. Learn more at Foxtails and Their Dangers.

FAQ: Dog Ear Infections

Can I Use OTC Ear Drops?

Only with your vet’s approval. Some ingredients can be harmful, especially if the eardrum is damaged.

How Often Should I Clean My Dog’s Ears?

  • Weekly or even more for dogs with chronic infections
  • Every 2–4 weeks for most dogs, or when any visible debris or smell is present

What Happens If I Don’t Treat It?

Untreated infections can lead to:

  • Permanent ear canal damage
  • Hearing loss
  • Chronic pain and secondary skin infections
