Vet Insights: The Overlooked Sign of a Dog Ear Infection You Shouldn’t Ignore
Dog ear infections are a common and often recurring health issue. Even if you recognize the typical symptoms, there’s one subtle sign many pet owners overlook—and this article will help you spot it early.
This article not only uncovers the commonly overlooked sign of ear infections in dogs but also dives into their causes, how they’re diagnosed, treatment options, and practical at-home care tips.
What Exactly is an Ear Infection in Dogs?
Ear infections in dogs typically result from bacterial or yeast overgrowth in the ear canal, and may also be triggered by parasites. Timely diagnosis and proper treatment are vital to avoid complications such as hearing loss and balance issues.
While dog ear infections are common, they often stem from underlying issues like allergies or excess moisture. Addressing these root causes is essential for long-term relief and preventing recurring infections.
Why Do Dogs Commonly Get Ear Infections?
A dog’s ear anatomy plays a key role in infection risk, as their L-shaped ear canal traps moisture more easily than the human ear.
Certain breeds, especially those with floppy or V-shaped ears, have limited air circulation, which increases moisture retention. Additionally, dogs with floppy ears are more prone to ear infections because their ears trap moisture. This warm, damp environment creates ideal conditions for bacterial and yeast overgrowth, making ear infections more likely.
Some dog breeds—such as Basset Hounds, Chinese Shar-Peis, Labradoodles, Beagles, Golden Retrievers, and Cockapoos—are more prone to ear infections due to their ear structure and moisture retention.
Underlying health issues like food or environmental allergies and hypothyroidism can also compromise the skin barrier in the ear canal. This weakened barrier makes it easier for bacteria or yeast to thrive, increasing the risk of recurring infections.
One Dog Ear Infection Symptom Most Owners Miss
One commonly overlooked symptom of a dog ear infection is unintentional eye movement, known as nystagmus. This rapid, involuntary eye motion may indicate inner ear involvement, which can affect balance and coordination.
Recognizing this subtle sign early can help ensure timely treatment and prevent more serious complications.
What are the Other Common Signs of Ear Infections in Dogs?
In this section, we’ll break down the signs of canine ear infections into two categories: early warning symptoms and more severe, advanced indicators.
Common early warning signs of canine ear infections
- Debris buildup in the ear canal (may resemble coffee grounds, especially with ear mites)
- Foul or yeasty odor coming from the ear
- Scabs or crusting in or around the ear
- Hair loss or flaky skin on the ear flap
- Redness and swelling of the ear canal or flap
- Visible discharge (waxy, dark brown, yellow, or pus-like)
- Frequent scratching or pawing at the affected ear
- Pain or yelping when the ear is touched
- Excessive head shaking or tilting
More severe indicators of ear infections in dogs
- Vomiting, often related to inner ear imbalance
- A head tilt that persists or worsens
- Partial or complete hearing loss
- Loss of balance, coordination issues, stumbling, or falling over
A Quick Guide to the Types of Ear Infections in Dogs
Contrary to common belief, a dog ear infection isn’t a one-size-fits-all condition—there are three distinct types, each affecting a different part of the ear. These include:
#1. Otitis Externa
Otitis externa is the most frequently diagnosed ear infection in dogs, affecting the outer ear canal. It’s usually triggered by bacteria, yeast, or parasites and commonly presents with redness, itching, severe ear flap scratching to the point of self-mutilation, and visible discharge.
#2. Otitis Media
Otitis media affects the middle ear and often develops as a complication of untreated otitis externa. Dogs may show signs of pain, head shaking, pawing at their head and/or ears, or even hearing loss as the infection progresses inward.
#3. Otitis Interna
Otitis interna involves the inner ear and can lead to serious symptoms such as balance problems, head tilt, and even neurological signs. This condition requires prompt veterinary treatment to prevent permanent damage.
Yeast vs. Bacterial Ear Infections in Dogs: What’s the Difference?
Yeast and bacterial ear infections in dogs can appear similar, but they have distinct characteristics:
- Yeast infections often produce a strong, musty odor and dark, waxy discharge.
- Bacterial infections typically cause lighter brown or yellow discharge and may be more associated with inflammation.
Veterinarians use microscopy to accurately diagnose the type, especially in cases involving the middle or inner ear, which are more commonly bacterial.
Ear mites, especially common in puppies, can trigger secondary bacterial or yeast infections in dogs. They cause intense itching and leave behind dark, gritty debris that resembles coffee grounds in the ear canal.
What Typically Triggers Ear Infections in Dogs?
Like many health issues in canines, ear infections typically stem from underlying causes. Below are the most common reasons dogs develop ear infections.
- Excessive moisture from swimming or bathing creates an ideal environment for bacteria and yeast
- Foreign bodies like grass awns or foxtails lodged in the ear canal
- Ear mites, especially in puppies, can cause irritation and secondary infections
- Trauma to the ear from scratching or injury
- Autoimmune diseases, such as lupus or pemphigus, that affect skin health
- Allergies to food, pollen, dust, or flea bites—major contributors to chronic infections
- Improper or excessive ear cleaning that damages the ear canal or alters its environment
- Wax buildup that traps moisture and debris, leading to microbial growth
- Endocrine disorders like hypothyroidism that affect skin and immune function
- Polyps or tumors in the ear canal that block airflow and promote infection
- Too much hair in the ear canal can cause a buildup of moisture and wax
How Do Vets Diagnose Ear Infections in Dogs?
When a dog exhibits signs of an ear infection, especially in chronic or severe cases, an accurate veterinary diagnosis is essential.
Your vet will begin by taking a thorough history, including when the symptoms started, their duration, any prior infections, and known allergies. This information serves as the foundation for creating a targeted, effective treatment plan tailored specifically to your dog’s condition and needs.
A comprehensive physical examination comes next, with careful inspection of the ear canal and surrounding tissue. This hands-on assessment is key to identifying the underlying problem and customizing the most effective treatment for your dog.
An otoscopic examination allows the veterinarian to closely inspect the ear canal and eardrum for signs of inflammation, damage, foreign bodies, or abnormal growths. If the ear is too painful, sedation may be required for a complete evaluation.
In addition, a microscopic examination (cytology) of ear debris helps identify bacteria, yeast, or ear mites, guiding accurate diagnosis and treatment.
In chronic or severe ear infections, culture and sensitivity testing help identify the specific bacteria or yeast involved and determine the most effective medication. Blood tests may also be conducted to uncover underlying issues such as allergies or hormonal imbalances.
Advanced imaging techniques like X-rays, CT scans, or MRIs may be recommended for severe or inner ear infections, especially when tumors or deeply embedded foreign bodies are suspected. These tools provide detailed views of the ear's internal structures. In cases where a tumor is suspected, a biopsy may be performed to confirm the diagnosis and guide treatment.
How Vets Conventionally Treat Dog Ear Infections
Effective treatment for dog ear infections depends on the type, severity, and any underlying causes, such as allergies or moisture buildup. A veterinarian can recommend targeted solutions, from medicated drops to dietary changes, to relieve symptoms and prevent recurrence.
The following are the conventional treatment methods for canine ear infections:
Professional ear cleaning is often the first step in treating dog ear infections, with veterinarians using medicated cleansers to remove wax, debris, and discharge. In more severe or painful cases, anesthesia may be necessary to ensure a thorough and stress-free cleaning process.
Topical medications such as prescription ear drops are commonly used to treat dog ear infections, targeting bacteria, yeast, and inflammation. These treatments often include antibiotics, antifungals, anti-inflammatories, and occasionally steroids for more effective relief.
For moderate to severe dog ear infections, veterinarians may prescribe oral medications to manage deeper or systemic issues. These may include antibiotics, antifungals, or anti-inflammatory drugs to reduce infection and promote lasting recovery.
When ear mites are the cause of a dog’s ear infection, antiparasitic medications are prescribed to eliminate the infestation. Because mites can spread easily, treatment is often recommended for all pets in the household to prevent reinfection.
Medicated ear cleansers approved by veterinarians are often recommended for at-home care to help remove debris and prevent future infections. Regular use supports ear hygiene and can be an effective part of ongoing ear health maintenance for dogs.
Surgery is rarely required for dog ear infections, but may be necessary in chronic, severe cases involving tumors, hematomas, or a closed ear canal. One such procedure, Total Ear Canal Ablation (TECA), involves removing the ear canal to eliminate persistent infection and discomfort.
To ensure the successful treatment of your dog’s ear infection, it’s essential to follow your veterinarian’s directions closely. Finishing the entire prescribed course of medication is key to fully clearing the infection and avoiding complications.
Can You Treat a Dog’s Ear Infection at Home?
For mild or early-stage ear infections, supportive care at home can help promote healing. If you're considering natural remedies, consult your veterinarian or a pet homeopathy specialist to ensure safe and effective treatment.
These home care practices can support your dog’s recovery:
Proper cleaning and gentle ear massage are key to maintaining your pet’s ear health.
Cleaning your dog’s ears at home can aid recovery, but it should only be done under the guidance of a veterinarian or qualified pet homeopathy specialist. Always use a professionally approved ear cleaning solution to ensure safety and effectiveness.
Carefully apply the cleaning solution into your dog’s ear canal, then gently massage the base of the ear to help break up wax and debris. Let your dog shake its head afterward to naturally expel the loosened material.
Cotton balls and gauze are safe and effective tools for cleaning your dog’s ears.
To safely clean your dog’s ears, gently use cotton balls or gauze to remove dirt and debris from the outer ear and ear flap. Avoid inserting cotton swabs into the ear canal, as they can push debris further in and risk damaging the eardrum.
Never clean deeper into your dog’s ears than your finger can comfortably reach. Practicing safe ear cleaning techniques protects the delicate ear canal and supports a smooth recovery.
Don’t skip drying—removing excess moisture after cleaning is essential for healthy canine ears.
Thoroughly dry your dog’s ears after cleaning to prevent moisture buildup and infection. Avoid inserting anything deep into the ear canal unless directed by a veterinarian. Gentle, surface-level care is key to maintaining healthy ears and avoiding accidental injury.
Afterwards, gently use a soft, clean cotton pad or tissue to wipe the inside of your dog's ear flap and outer canal, absorbing any excess liquid.
A recovery collar can help prevent self-inflicted injury and support your dog’s healing process.
If your dog is excessively scratching due to an ear infection, using a recovery collar (also known as a cone or an Elizabethan collar) can help prevent further irritation or injury. This protective measure gives the ears time to heal while minimizing the risk of complications.
