Effective Ways to Treat Yeast Infection in Dog's Ears
Dec 17,2024 | puaintapets
Yeast infections in your dog's ears are a common problem that can cause discomfort and irritation. These infections are usually caused by an overgrowth of yeast, often triggered by factors such as allergies, moisture or a weakened immune system. Fortunately, yeast infections in your dog's ears can be effectively treated with the right approach. In this guide, we'll give you everything you need to know about treating and preventing yeast infections in your furry friend.
What is a Yeast Infection in Dogs’ Ears?
A yeast infection in a dog’s ear occurs when yeast, a type of fungus, multiplies excessively. Yeast naturally exists in a dog’s body, but when the balance is disrupted, it can lead to infections. Dogs with floppy ears, like Cocker Spaniels or Basset Hounds, are particularly prone due to the warm, moist environment within their ear canals.
Causes of Yeast Infections in Dogs' Ears
1. Ear canal environment
Dogs' ear canals have a special, L-shaped structure that easily allows excess moisture and debris to accumulate within. If the owner does not clean the dog's ears regularly, or if the cleaning method is not appropriate, it will lead to the deterioration of the environment inside the ear canal, providing conditions for yeast to multiply. In addition, some dogs are at increased risk of yeast infections due to genetic or breed traits, such as pendulous-eared breeds, whose ear canals are more prone to moisture and less likely to be ventilated.
2. Immunocompromised
When a dog's skin immunity is lowered, its ability to fight off yeast is also weakened, making it easier for yeast to invade and infect. This can be related to the dog's diet, lifestyle and underlying health issues.
3. Allergic reactions
Allergies are one of the most common causes of yeast infections in dogs, especially to fleas, food or substances in the environment. Allergies can cause skin irritation and make the skin more oily, providing a favourable environment for yeast to grow.
4. Other factors
Dogs are also susceptible to infection after coming into contact with an animal suffering from a yeast infection. Yeast can be spread to dogs through direct contact or indirect contact. In addition, certain medications, heavy metals and environmental toxins can damage the beneficial bacteria in your dog's intestinal tract, thus allowing yeast to grow.
5. Dietary factors
A diet high in carbohydrates may worsen yeast because carbohydrates produce the sugar that feeds the yeast.
6. Humid environment
Dogs are susceptible to yeast infections in humid environments, such as after regular swimming or bathing, if the moisture in the ear canal is not dried in time, yeast can easily grow.
To prevent yeast infections in dogs‘ ears, owners need to clean their dogs’ ears regularly, keep the ear canals dry and ventilated, avoid exposing their dogs to possible allergens, as well as provide a high-quality diet. If your dog is already showing signs of infection, seek medical attention and follow your vet's advice.
What are Symptoms of Yeast Infection in Dogs?
1. Ear symptoms
- Discharge: brown or black discharge appears in the ear, which is a mixture of substances produced by the inflammatory reaction caused by the yeast infection.
- Odour: The ears emit a particular foul smell, which is rather strong and pungent, somewhat like fermentation.
- Itching: The dog will scratch the ears frequently or shake its head. In severe cases, the skin around the ears may become hairless, red and swollen or even broken.
- Redness and swelling: Gently pulling up the dog's ear canal, you can observe that the skin inside the ear canal and around the ear canal may appear red and swollen.
- Thickening of the ear canal: In cases of chronic yeast infections, the skin of the ear canal may thicken due to inflammation and tissue growth.
2. Skin symptoms
- Dry/greasy skin: Yeast infection may cause an imbalance in the oil production of the skin, which may appear dry or greasy.
- Changes in skin appearance: The skin at the site of infection may appear red, crusty, flaky or dandruffy.
- Hair loss: Hair may fall out of the infected area.

3. Behavioural changes
- Ear sensitivity: Your dog may show pain or hypersensitivity when touched in the ear.
- Hearing changes: If the yeast infection affects the middle or inner ear, the dog may experience hearing loss and become less responsive to sound.
- Head shaking or tilting: Dogs may experience head shaking or tilting due to ear discomfort.
- Loss of balance: An inner ear infection may affect your dog's sense of balance, causing him to walk unsteadily or experience abnormal back and forth eye movements (nystagmus).
If you notice any of these symptoms in your dog, it is recommended that you take him to the vet promptly so that he can be accurately diagnosed and treated accordingly.

Diagnosing Yeast Infections in Dogs’ Ears
Veterinarians diagnose yeast infections through:
- Physical Examination: Checking for redness, swelling, or abnormal discharge.
- Microscopic Analysis: Examining ear swabs under a microscope to confirm yeast presence.
- Culture Testing: For recurring or severe cases, identifying the exact type of yeast.
Veterinary Treatments for Severe Yeast Infections
For more advanced cases, veterinarians may recommend:
-
Medications:
- Antifungal ear drops or ointments containing miconazole or clotrimazole.
- Oral antifungal medications for systemic infections.
-
Professional Ear Cleaning:
- Deep cleaning performed under sedation to remove wax and debris.
-
Anti-inflammatory Drugs:
- Veterinarians often prescribe anti - fungal medications for treating yeast infections. These can come in the form of ear drops or ointments. Commonly used anti - fungal agents include ketoconazole and miconazole. Follow the vet's instructions precisely regarding the dosage and frequency of application. Usually, the treatment may need to be continued for a few weeks to completely eliminate the yeast infection.
-
Treatment of Underlying Conditions:
- Addressing allergies or hormonal imbalances to prevent recurrence.
Home Remedies for Mild Yeast Infections
- Dietary Adjustments
In some cases, a change in the dog's diet can also be helpful. A diet rich in high - quality proteins and low in carbohydrates may be beneficial. Some dogs may be allergic to certain ingredients in their food, which can contribute to ear problems. Consider switching to a hypoallergenic diet if the vet suspects an allergy - related cause. - Environmental Management
Keep the dog's living environment clean and dry. Moisture can promote the growth of yeast. Ensure that the dog's bedding is regularly washed and dried. Also, if the dog likes to swim, dry its ears thoroughly after each swim. -
Apple Cider Vinegar Dilution
Mix equal parts water and apple cider vinegar. Use a cotton ball to apply the solution, avoiding deep insertion into the ear. - Coconut Oil Application
Coconut oil has natural antifungal properties. Apply a small amount to soothe irritation.

How to Adjust Dog's Diet for Yeast Infection in the Ear?
I. Choose high-quality dog food
- High quality protein source
Choose a dog food that has high-quality animal proteins such as chicken, fish or beef as its main ingredient. These high-quality proteins help boost your dog's immune system, which in turn helps him fight off yeast infections in the ears. Chicken, for example, is rich in a number of essential amino acids, which are essential for building and repairing body tissues, helping to maintain the normal physiological functions of your dog's body.
- Avoid low quality grains
Cut down on dog foods that contain high amounts of grains that can cause allergic reactions, such as corn, wheat and soy. These grains may cause an inflammatory reaction in your dog's body and affect their ear health. Some dogs may be allergic to the gluten in these grains, which can aggravate yeast infections in the ears.
II. Increase specific nutrients
- Fatty acids
Supplement with foods rich in omega-3 fatty acids. For example, you can add fish oil supplements to your dog or choose a dog food that contains fish oil. Omega-3 fatty acids have anti-inflammatory properties that can reduce inflammation in the ear and help to inhibit yeast overgrowth.
- Vitamins and Minerals
Make sure your dog is getting enough nutrients such as vitamin C, E and zinc. Vitamin C is an antioxidant that helps boost the immune system; vitamin E also has antioxidant properties that are beneficial to skin and ear health; and zinc is a trace mineral that is essential for maintaining the normal function of the skin and mucous membranes. This can be met by giving your dog fresh fruits and vegetables (e.g. apples, carrots, etc., but be careful with moderation as some can be potentially risky for dogs) or specialised pet vitamin supplements.
III. Consider special diets
- Hypoallergenic diets
If you suspect that your dog's ear yeast infection is related to a food allergy, try a hypoallergenic diet. This diet is usually a dog food made using a special protein source (such as duck, venison, and other uncommon meats) and a single carbohydrate source (such as sweet potatoes). This special diet can help eliminate possible food allergens and reduce the body's allergic reaction, which can help with ear yeast infections.
- Homemade diets (under the guidance of a veterinarian)
Homemade diets can be created for dogs under the guidance of a veterinarian. For example, cook a mixture of chicken, vegetables (e.g. broccoli, pumpkin, etc.) and moderate amounts of brown rice. This allows precise control over the composition of the food and avoids substances that may cause allergies or aggravate infections. However, homemade diets need to be nutritionally balanced to ensure that the various nutritional needs of your dog are met.
It is important to note that dietary modifications are only part of the aids in treating yeast infections in your dog's ears, and need to be combined with other therapeutic recommendations from your veterinarian, such as the use of antifungal medications and cleaning of the ears, to achieve better results.
FAQs
What not to give a dog with a yeast infection?
1. High-sugar foods
Yeast feeds on sugar and foods high in sugar will promote yeast growth and reproduction. For example, candies, high sugar pet snacks, and some commercial pet foods that contain a lot of added sugar should be avoided.
2. High-carbohydrate foods (excessive intake)
Large amounts of carbohydrates are broken down into sugar during digestion, which provides nutrients for the yeast. Carbohydrate-rich grains like corn and wheat may not be conducive to the recovery of a dog with a yeast infection if they make up too high a percentage of a dog's diet. However, it is not appropriate to remove carbohydrates completely because dogs need a certain amount of carbohydrates to maintain their energy balance, so it is important to control the proportion.
3. Foods that may cause allergies
Allergic reactions can lead to changes in the skin and ear canal environment that favour yeast growth. Common foods that may cause allergies in dogs include beef, dairy, and soy. If the dog itself is allergic to these foods, ingestion may aggravate the symptoms of a yeast infection.
How to tell if dog ear infection is yeast or bacterial?
Observation of secretions
I.Colour
Yeast Infection: you will usually see a brown or black discharge from your dog's ears. This is due to the mixture of substances produced by the yeast infection that gives this distinctive colour.
Bacterial infections: the discharge may be yellow or green in colour, which is a colour feature caused by a bacterial infection that triggers an inflammatory response, with purulent material in it, among other things.
II. Texture
Yeast infection: the discharge tends to be greasy, sticky and sometimes waxy. This is the result of yeast proliferating in the ear canal and mixing with the epithelial cells, oils, etc. of the ear canal.
Bacterial infection: the discharge is thinner in texture and sometimes purulent. This is due to a bacterial infection that triggers suppurative inflammation, resulting in a thinner and pus-laden discharge.
