Sep 20,2024 | puaintapets
Ear infections in dogs are a common health problem that involves inflammation of the outer, middle and inner ear canals. Otitis externa is the most common type and is usually caused by ear mites, bacteria, fungal infections or foreign objects. Middle ear infections and inner ear infections are less common, but can lead to more serious complications such as hearing loss and balance problems . Symptoms of ear infections include redness, swelling, odor, discharge, itching, pain, head shaking and blockage of the ear canal. Dogs may seem agitated or become more aggressive due to ear discomfort. In some cases, ear infections may affect a dog's appetite and behavior.
How to Tell If My Dog Has an Ear Infection
Determining Ear Infections in Dogs
Dog ear infections are usually accompanied by a range of typical symptoms, and you can tell if your dog may be suffering from an ear infection by looking at the following areas.
-
Behavioral changes
Your dog may shake his head frequently, scratch his ears, or rub the area around his ears, usually due to discomfort or itching inside the ears.
-
Changes in Appearance
The inside or outside of the ear may appear red, swollen, itchy, have increased discharge (which may be yellow, brown or black) and sometimes have an odor.
-
Auditory Reactions
Dogs may be unresponsive to sound, which may be due to an ear infection that is affecting their hearing.
-
Tilted ears
If your dog has a severe ear infection, they may develop a tilted ear, which is usually due to pain in the ear or balance issues.
-
Loss of Balance
If the infection spreads to the inner ear, your dog may experience balance problems and appear disoriented.
-
Unusual Vocalization
Dogs in pain often whine or whimper, and ear infections can be particularly painful for them.
-
Decreased Appetite
If your dog is in pain or discomfort, especially if the infection has caused systemic issues like fever, they may lose interest in food.
1.Common Symptoms of Dog Ear Infections
When your dog has an ear infection, they will likely show some of the following signs:
-
Scratching and Head Shaking: One of the earliest and most common signs is frequent scratching at the ear and shaking of the head.
-
Ear Discharge: Infected ears often produce a discharge that may be brown, yellow, or black in color. This is usually a sign of yeast or bacterial infections.
-
Foul Odor from the Ear: A strong, unpleasant odor coming from the ear is another telltale sign of infection.
-
Redness and Swelling: The ear canal may appear inflamed, and you might notice redness around the outer ear.
-
Sensitivity to Touch: Your dog may yelp or pull away when you touch the affected ear due to discomfort or pain.
2.Types of Dog Ear Infections
There are three main types of ear infections that can affect dogs, and knowing which one your dog might have helps in determining the severity of the problem.
-
Outer Ear (Otitis Externa): This is the most common type of ear infection in dogs. It involves inflammation of the outer ear canal and is often caused by bacteria, yeast, or ear mites.
-
Middle Ear (Otitis Media): This type of infection occurs when the infection spreads from the outer ear to the middle ear. This can lead to more severe symptoms like balance issues and pain.
-
Inner Ear (Otitis Interna): The most serious form of ear infection, it occurs when the infection spreads deep into the ear canal. Inner ear infections can lead to deafness, loss of balance, and neurological problems.
-
Bacterial Ear Infection: this infection is usually accompanied by a foul-smelling, tan colored discharge and the dog may shake his head or scratch his ears frequently. Your veterinarian may be able to identify the specific type of bacteria through an ear swab culture and select the appropriate antibiotic accordingly.
-
Yeast Infection: A yeast infection (usually Candida) can cause an itchy, reddened ear canal, sometimes accompanied by a black or brown, greasy discharge. Your veterinarian may use a microscope to examine ear canal scrapings for the presence of yeast.
-
Allergic Ear Disease: Allergies may cause inflammation of the ear canal, accompanied by redness, swelling, and discharge. Allergic ear disease may require long-term management, including avoidance of known allergens and use of anti-inflammatory medications.
3. Causes of Ear Infections in Dogs
A variety of factors can lead to ear infections in dogs. Some common causes include:
-
Allergies: Many dogs develop ear infections due to allergies to food or environmental factors such as pollen, dust, or mold. These allergies cause inflammation, making the ear more prone to infection.
-
Excess Moisture: Dogs that love to swim or those living in humid climates are more likely to get ear infections due to trapped moisture in their ears.
-
Ear Mites: These tiny parasites can cause intense irritation and lead to infections.
-
Foreign Bodies: Grass seeds, dirt, or other objects lodged in the ear canal can cause irritation and lead to infection.
-
Bacterial and Fungal Infections: These microorganisms can multiply in the warm, moist environment of a dog’s ear, especially when the ear is inflamed or dirty.

These pathogens can cause otitis externa, otitis media, and other ear diseases in dogs, and symptoms may include itching of the ear canal, head shaking, increased discharge from the ear canal, and odor. Treatment usually involves targeted medication and ear canal cleaning depending on the type of pathogen. Preventive measures include cleaning your dog's ears regularly, keeping the ear canals dry, and avoiding water in the ears.
How Can I Tell If My Dog's Ear Problem Is a Common Infection or an Otitis Media?
The basis for distinguishing between a common infection and an otitis media
-
Comparison of Symptoms
A common ear infection (otitis externa) usually presents with redness of the ear canal, odor, itching and scratching behavior. Otitis media may be accompanied by more serious symptoms such as head shaking, ear pain, hearing loss, abnormal facial expressions, and possibly even eyelid twitching or balance disorders.
-
Clinical Examination
The veterinarian may look inside the ear canal by visual inspection, palpation and use of an otoscope. Otitis media may result in congestion or perforation of the eardrum, which are not easily visualized during routine external ear canal examination and may require further diagnostic testing such as x-rays or CT scans.
-
Therapeutic response
Common infections usually respond well to appropriate ear cleaning and topical antibiotic therapy. If symptoms do not improve or worsen with treatment, this may indicate that the infection has spread to the middle ear.
-
History Considerations
The anatomy of your dog's ear canal, the presence of a history of ear mite infections, and the presence of environmental factors that cause the ear canal to become moist (such as frequent bathing or swimming) are all important factors in assessing the risk of otitis media.
If you suspect that your dog has an ear problem that goes beyond a common infection, you should contact your veterinarian immediately for professional diagnosis and treatment. Your veterinarian will use your dog's specific symptoms and examination results to determine whether or not he has an otitis media, and will develop a treatment plan accordingly.
