Ear infections are among the most common reasons dogs end up at the vet, and a lot of them are preventable with routine attention. This guide covers checking and caring for your dog’s ears properly.

What a Healthy Ear Looks Like
A healthy ear canal looks clean and pale pink inside, without heavy wax buildup, redness, or a noticeable odor. Some dogs naturally produce a bit more wax than others, so knowing your own dog’s baseline helps you spot when something’s actually changed.
How to Check Your Dog’s Ears
Gently lift the ear flap and look inside without inserting anything into the canal itself. You’re checking for color, odor, discharge, and how your dog reacts to being touched near the ear.
A dog who suddenly seems sensitive or pulls away during a normally tolerated check is telling you something worth paying attention to.
Ear Cleaning: When and How
Not every dog needs regular ear cleaning, and over-cleaning can actually disrupt the ear’s natural balance and increase infection risk. Dogs with floppy ears, heavy wax production, or a history of infections generally benefit more from routine cleaning than dogs with upright ears and minimal wax.
Use a vet-approved ear cleaner, never water, cotton swabs, or homemade solutions, and only clean the visible part of the ear canal rather than probing deeper.
Ear Shape and Airflow
Upright ears allow air to circulate through the canal freely, which naturally discourages the moist environment infections need to take hold. This is part of why breeds with naturally upright ears tend to have fewer ear problems overall than floppy-eared breeds, independent of any other care differences.
Breeds With Higher Ear Infection Risk
Floppy-eared breeds trap moisture and reduce airflow to the ear canal, creating conditions that bacteria and yeast thrive in. Dogs with excess hair growing inside the ear canal face a similar issue, since the hair can trap wax and debris. Dogs who swim frequently are also at higher risk, since water trapped in the ear canal creates the same moist environment.
Signs of an Ear Infection
Scratching at the ear, head shaking, a strong odor, discharge, redness, swelling, or visible pain when the ear is touched all point to a likely infection. Left untreated, ear infections can become painful and, in some cases, affect hearing or balance if they progress deep enough into the ear structure.
Yeast Infections vs Bacterial Infections
Both cause similar symptoms, but yeast infections often have a distinctly musty or “corn chip” smell, while bacterial infections may produce a different odor and sometimes a more colored discharge. Only a vet can properly identify which one, or whether it’s a combination of both, which matters for choosing the right treatment.
Ear Mites
More common in puppies and dogs with heavy outdoor exposure, ear mites cause intense itching and a dark, coffee-ground-like discharge. They’re highly contagious between pets in the same household, so a vet visit and treatment plan usually needs to cover every pet, not just the one showing symptoms.
Drying Ears After Baths and Swimming
Thoroughly drying the outer ear and gently drying just inside the ear opening after any water exposure meaningfully reduces infection risk, particularly for floppy-eared or swimming-prone dogs. A few seconds of extra attention here prevents a common, recurring problem for water-loving dogs.
Handling a Painful Ear Carefully
A dog with a painful ear infection may flinch, growl, or even snap when the ear is touched, not out of aggression but out of genuine discomfort. Approach handling gently, and don’t force a full inspection if your dog is clearly in pain, since your vet can examine the ear properly with tools designed for the job.
When to See a Vet
Any of the infection signs above warrant a vet visit rather than home treatment, since the wrong cleaner or product can worsen certain types of infections. Recurring ear infections, more than two or three times a year, are worth investigating for an underlying cause, like allergies, rather than treating each episode as an isolated event.
Preventing Recurring Infections
For dogs prone to repeat infections, your vet might recommend a regular preventive cleaning schedule, addressing an underlying allergy, or in some cases having excess ear hair professionally removed. Identifying and managing the root cause tends to work better long-term than repeatedly treating each new infection as it appears.
Common Mistakes in Ear Care
Using cotton swabs inside the ear canal. This can push debris deeper or damage the delicate ear structure, and is best avoided entirely.
Cleaning too frequently in a dog who doesn’t need it. Over-cleaning can disrupt the ear’s natural protective balance and increase irritation.
Assuming head shaking is just a habit rather than a symptom. Persistent head shaking almost always has a specific cause worth investigating.
Frequently Asked Questions
How often should I clean my dog’s ears? This varies by breed and individual dog, from never needed for some low-risk dogs to weekly for dogs prone to buildup, so it’s worth asking your vet for a recommendation specific to your dog.
Can I use a human ear cleaning product on my dog? No, dog ear canals have a different pH and structure than human ears, and human products aren’t formulated appropriately for them.
Is it normal for my dog to shake their head sometimes? Occasional head shaking is normal, but frequent or persistent shaking usually points to irritation, infection, or a foreign object that needs a vet’s attention.
The Bottom Line
Most ear problems are preventable with routine checks and appropriate cleaning, but recognizing the signs of an actual infection early makes treatment far more straightforward.
