A yeast infection in dogs, medically known as Malassezia dermatitis, is a common and uncomfortable condition that affects the skin and ears. Understanding what triggers and exacerbates these infections is crucial for effective management and treatment. This article will provide a comprehensive guide on what not to give a dog with a yeast infection, covering dietary considerations, environmental factors, and other potential irritants.
Understanding Yeast Infections in Dogs
Yeast infections in dogs are primarily caused by an overgrowth of the Malassezia globosa yeast, a fungus naturally present on a dog’s skin. Under normal circumstances, the yeast lives in harmony with other microorganisms, but certain factors can disrupt this balance, leading to an overgrowth and subsequent infection.
Several factors can contribute to a yeast infection. These include:
- Underlying allergies: Food or environmental allergies often weaken the skin’s barrier function.
- Weakened immune system: Conditions that compromise the immune system can make a dog more susceptible to yeast overgrowth.
- Antibiotic use: Antibiotics can kill beneficial bacteria, creating an environment where yeast can thrive.
- Skin folds: Breeds with skin folds are prone to yeast infections because the folds create warm, moist environments that favor yeast growth.
- High humidity: Humid environments can also contribute to yeast overgrowth.
Recognizing the symptoms of a yeast infection is vital for prompt treatment. Common signs include:
- Intense itching and scratching.
- Redness and inflammation of the skin.
- Hair loss, particularly around the ears, paws, and groin.
- A distinct, musty odor.
- Greasy or scaly skin.
- Hyperpigmentation (darkening of the skin).
- Chronic ear infections.
Dietary Considerations: What to Avoid Feeding Your Dog
Diet plays a significant role in managing yeast infections. Certain foods can fuel yeast growth, while others can help support the immune system and reduce inflammation. Therefore, being mindful of your dog’s diet is paramount when dealing with a yeast infection.
Sugars and Simple Carbohydrates
Yeast thrives on sugar. Therefore, it’s crucial to eliminate or significantly reduce the intake of simple carbohydrates and sugars. This includes:
- Processed dog treats: Many commercial dog treats are loaded with sugars, corn syrup, and other sweeteners. Always read the ingredient list carefully and opt for treats with minimal processing and no added sugars.
- Grains with high glycemic index: White rice, corn, and wheat are high in carbohydrates that break down into sugar quickly. These can contribute to yeast overgrowth.
- Fruits with high sugar content: While fruits can be healthy in moderation, those high in sugar, such as grapes, bananas, and mangoes, should be limited or avoided during a yeast infection.
- Honey and syrups: Avoid adding honey, maple syrup, or any other sweeteners to your dog’s food.
Foods Containing Yeast
It may seem counterintuitive, but feeding your dog foods containing yeast can sometimes exacerbate a yeast infection, although the effect is debated. The theory is that it introduces more yeast into the system.
- Brewers yeast: Brewers yeast is a common ingredient in some dog foods and supplements. While it offers nutritional benefits, it might be best to avoid it while the dog is battling a yeast infection.
- Certain baked goods: Avoid feeding your dog bread, pastries, or other baked goods that contain yeast.
Processed Foods and Artificial Additives
Processed foods often contain ingredients that can disrupt the gut microbiome and weaken the immune system. These include:
- Artificial colors and flavors: These additives can trigger allergic reactions and inflammation, which can worsen yeast infections.
- Chemical preservatives: Similar to artificial colors and flavors, chemical preservatives can disrupt the gut microbiome and weaken the immune system.
- Low-quality fillers: Corn, soy, and wheat are common fillers in low-quality dog foods. These can be difficult to digest and may contribute to inflammation and yeast overgrowth.
Potential Allergens
Food allergies can compromise the skin’s barrier function, making a dog more susceptible to yeast infections. Identifying and eliminating potential allergens is crucial. Common allergens in dogs include:
- Beef: Beef is a common allergen in dogs and should be avoided if your dog has a known or suspected allergy.
- Dairy: Dairy products can also trigger allergic reactions in some dogs.
- Chicken: Chicken is another common allergen, particularly in dogs with sensitivities to poultry.
- Lamb: Lamb can be an allergen, though less common than beef or chicken.
Environmental Factors and Products to Avoid
Besides diet, certain environmental factors and products can contribute to or worsen yeast infections in dogs.
Harsh Shampoos and Soaps
Using harsh shampoos or soaps can strip the skin of its natural oils, leading to dryness and irritation. This can compromise the skin’s barrier function and make it more susceptible to yeast overgrowth.
- Shampoos with sulfates: Sulfates are harsh detergents that can dry out the skin. Avoid shampoos containing sulfates, such as sodium lauryl sulfate (SLS) and sodium laureth sulfate (SLES).
- Fragrances: Fragrances can irritate sensitive skin and should be avoided.
- Alcohol-based products: Alcohol can also dry out the skin and should be avoided in shampoos and other topical products.
Over-Bathing
While bathing is essential for hygiene, over-bathing can remove the skin’s natural oils and disrupt the skin’s microbiome. This can create an environment favorable to yeast overgrowth.
- Limit bathing frequency: Bathe your dog only when necessary, typically no more than once or twice a month.
- Use a gentle shampoo: Choose a gentle, hypoallergenic shampoo specifically formulated for dogs with sensitive skin.

- Wash bedding frequently: Wash your dog’s bedding regularly in hot water to kill yeast and bacteria.
Other Considerations
Beyond diet and environmental factors, several other considerations are important for managing yeast infections in dogs.
Antibiotics
While antibiotics can be necessary for treating bacterial infections, they can also disrupt the gut microbiome and create an environment where yeast can thrive.
- Use antibiotics judiciously: Only use antibiotics when necessary and prescribed by a veterinarian.
- Consider probiotics: If your dog needs antibiotics, talk to your veterinarian about supplementing with probiotics to help restore the balance of gut bacteria.
Steroids
Steroids, such as prednisone, can suppress the immune system, making a dog more susceptible to yeast infections.
- Use steroids judiciously: Only use steroids when necessary and prescribed by a veterinarian.
- Monitor for signs of yeast infection: If your dog is on steroids, monitor them closely for signs of a yeast infection.
Stress
Stress can weaken the immune system and make a dog more susceptible to infections, including yeast infections.
- Minimize stress: Create a calm and stable environment for your dog.
- Provide plenty of exercise and mental stimulation: Regular exercise and mental stimulation can help reduce stress.
- Consider calming supplements: Talk to your veterinarian about using calming supplements, such as L-theanine or chamomile, to help reduce stress.
Certain Medications
Some medications can increase the risk of yeast infections.
- Discuss medications with your veterinarian: Always inform your veterinarian about all medications your dog is taking, including over-the-counter medications and supplements.
- Monitor for side effects: Be aware of the potential side effects of medications, including an increased risk of yeast infections.

The key is to proactively manage the factors that promote yeast growth and support your dog’s immune system. Always consult with your veterinarian for a proper diagnosis and treatment plan.
What types of carbohydrates should I avoid feeding my dog with a yeast infection?
Avoid feeding your dog simple carbohydrates like white rice, white bread, corn, and potatoes. These types of carbohydrates break down quickly into sugars, which fuel yeast growth. Opt for complex carbohydrates in moderation only if directed by your veterinarian.
Instead, focus on a diet high in protein and low in carbohydrates. Work with your veterinarian to determine the right macronutrient balance. If you must include carbohydrates, choose options like sweet potato or brown rice in very small quantities, ensuring they don’t exacerbate the yeast infection symptoms.
Are there specific fruits that can worsen a yeast infection in dogs?
Yes, certain fruits can contribute to yeast overgrowth due to their high sugar content. Avoid giving your dog fruits such as grapes, bananas, mangoes, and other sweet fruits. These fruits can elevate blood sugar levels, providing a favorable environment for yeast to thrive.
While some fruits are generally safe in small amounts for healthy dogs, when dealing with a yeast infection, it’s best to err on the side of caution and eliminate fruits from their diet. Your veterinarian can advise on the safety of specific fruits depending on the severity and location of the yeast infection.
Should I avoid giving my dog commercial dog treats if they have a yeast infection?
Many commercial dog treats contain ingredients that can exacerbate a yeast infection. Be wary of treats that list corn, wheat, soy, sugar, or artificial sweeteners as primary ingredients. These ingredients provide readily available sugars and starches for yeast to feed on.
It’s recommended to eliminate commercial treats entirely while treating a yeast infection. If you want to give your dog a treat, consider using small portions of lean meat, like cooked chicken breast, or vegetables approved by your veterinarian. Alternatively, look for hypoallergenic or grain-free treats with limited ingredients under veterinary supervision.
Are dairy products like cheese and yogurt bad for a dog with a yeast infection?
Dairy products can be problematic for dogs with yeast infections. Many dogs are lactose intolerant to some degree, and dairy can cause digestive upset, which can indirectly weaken the immune system and make the dog more susceptible to yeast overgrowth. Additionally, the sugars in dairy can directly feed the yeast.
While some proponents suggest that plain, unsweetened yogurt can be beneficial due to its probiotic content, it’s essential to proceed with caution. Consult your veterinarian before introducing yogurt, as even unsweetened varieties contain some lactose. Alternatives like coconut yogurt, if tolerated, may be a better option, but always check the ingredient list for added sugars.
Can I give my dog supplements with added sugars or fillers if they have a yeast infection?
No, you should avoid giving your dog supplements that contain added sugars, artificial sweeteners, or unnecessary fillers. These ingredients can contribute to yeast overgrowth. Always scrutinize the ingredient list of any supplement before administering it to your dog.
Choose supplements that are specifically formulated for dogs and contain only essential ingredients.
