What Are The Best Anti-Fungal Herbs For Dogs?

K9 Yeast Defense is a dog yeast supplement containing natural anti-fungal ingredients scientifically proven to work:

  • Caprylic Acid For Dogs is a naturally occurring fatty acid with proven antifungal properties. It can help combat yeast overgrowth in the dog's body. Here are some ways that caprylic acid helps dogs with yeast:

    Antifungal Properties: Caprylic acid is known for its potent antifungal properties. It can help inhibit the growth of yeast, including the common Candida species responsible for many dog yeast infections.

    Balances Gut Flora: It supports a healthy balance of microorganisms in the gut by targeting harmful yeast overgrowth. This is essential as an overgrowth of yeast can disrupt the natural balance of the intestinal flora.

    Supports Digestive Health: Caprylic acid for dogs can promote better digestion and nutrient absorption, which is beneficial for overall health. A well-functioning digestive system can help prevent yeast overgrowth.

  • Pau d'Arco For Dogs (Tabebula heptaphylla) contains compounds with antifungal and immune-stimulating properties. Here are some ways that pau darco helps dogs with yeast:

    Antifungal Properties: Pau d'arco contains compounds, such as lapachol and beta-lapachone, that have demonstrated antifungal properties. These components can help inhibit the growth of yeast, including Candida, which is a common cause of yeast infections in dogs.

    Immune Support: Pau d'arco is believed to have immune-enhancing properties. By strengthening the immune system, it can assist the body in combating yeast overgrowth and preventing recurrent infections.

    Anti-Inflammatory: Inflammation often accompanies yeast infections, leading to symptoms like itching and discomfort. Pau d'arco's anti-inflammatory properties can help alleviate these symptoms, improving your dog's comfort.

    Supports Gut Health: Pau d'arco for dogs may also support a healthy gastrointestinal tract, which is essential in preventing the overgrowth of yeast in the digestive system.

  • Grapefruit Seed Extract contains compounds that exhibit potent antifungal activity, especially in the gastrointestinal tract where yeast issues often originate.

  • Echinacea Root (Echinacea angustifolia) is known for its immune-boosting properties. It can enhance the dog's immune system, helping it better fight off yeast-related problems.

  • Oregano is a natural herb with strong antimicrobial and antifungal properties. It can help control yeast overgrowth in the dog's system.

The blend of ingredients in K9 Yeast Defense work synergistically to promote a balanced internal environment for dogs combating yeast infections. We add Garlic Bulb Concentrate to help reduce inflammation in the mouth and gastrointestinal tract, while Sodium Copper Chlorophyllin helps to detoxify the liver and the intestinal tract. Essential minerals Selenium and Zinc, both in citrate form for optimal absorption, promote liver health and stimulate immune response. Our Proprietary Enzyme Blend supports the digestion for optimal nutrient absorption, helping to relieve your dog's yeast symptoms from the inside out.


"Graydon developed a yeast overgrowth after a large allergic reaction to Mayfly bites. I’m not sure what the connection is. His belly, paws and anus became covered with yeast. He was super itchy and uncomfortable. I googled and found Ask Ariel. As a nutritionist, I was already quite knowledgeable about supplements and also quite wary. As soon as I read about all the products Ask Ariel had to offer, I knew I had the right place! I started Graydon on the recommended yeast protocol as well as a raw diet. It all worked. After about a year I eased him back to kibble and slowly came off all supplements except the probiotics. He remains yeast free only flaring up in May when the Mayflies are biting! Thanks so much to your team for such smart and clean products and for caring so much!" - Caroline, New York

Graydon uses the following products from Ask Ariel: Power Probiotic, AllerEaze, K9 Yeast Defense, and Olive Leaf Extract.

Dog Yeast Infection Symptoms

What are the symptoms of a yeast infection in dogs? Typically, dogs experience chronic skin infections (pyoderma), skin redness, paw yeast infections, doggie odor, chronic ear infections, thickened skin (often called "elephant skin"), darkened skin (hyperpigmentation), and behaviors like paw chewing or genital licking. Most dogs have been diagnosed with yeast infections in the groin, ears, between the toes or under the armpits.

If your veterinarian has previously diagnosed yeast or your pet has taken prednisone or antibiotics, this can lead to yeast overgrowth because these medications kill the good bacteria that combat yeast. That is why your vet might prescribe antifungal medication when antibiotics are needed.

Dog Skin Yeast Infection Symptoms
  • Constant licking and scratching
  • Musty, smelly "cheese" odor even after bathing
  • Discoloration/darkening of the skin and fur
  • Redness of the skin
  • Chewing on itchy paws

  • Yeast Infections in Dog's Ears
  • Scratching at itchy ears
  • Tilting its head
  • Chronic ear infections
  • Wax residue and/or scabbing at the ear opening

  • Dakota

    "I want to let you know how great Dakota, our Golden Retriever that we rescued, is doing. When we got him, he had bad ear infections that he had for months, and his skin was so black in the armpit and groin areas that we thought it was ground in dirt. He also had acid reflux and would bring up bile several times a day. It has taken several months, but the blackened skin (from yeast) is almost back to normal thanks to K9 Yeast Defense. I wish we had taken “before” pictures of his skin because the difference is remarkable. This is the best supplement for dogs with yeast infections. And, for his acid reflux, we started using your supplements (Power Probiotic, K9 Digestive Enzymes, Gastro ULC and Soothing Digestive Relief). I can’t forget to mention using your food recommendations. His ears didn’t start to clear up until we got him eating food that he could tolerate. Thank you so much for your supplements and all your help. Dakota is a much happier dog thanks to you!" - Pat & Tim, Pennsylvania

    K9 Yeast Defense Helps Eliminate Doggie Odor

    Yeast thrives in warm, moist environments, making the summer months an ideal breeding ground for these pesky fungi. Factors such as increased humidity, swimming in lakes or ponds, and excessive moisture trapped in skin folds can contribute to yeast overgrowth in dogs during this time of year. If your pup enjoys a dip in the water, be mindful that moisture trapped in their coat can exacerbate yeast growth.


    "My beautiful white doggie always keeps himself clean. He loves to be in the water. We began to notice that he smelled really bad on his neck. It was coming from under his collar. He loves to swim at doggie day care and we finally realized that his skin was never drying out after swimming. It was giving him a terrible, musty odor. We tried removing his collar, but the odor would just come back. We started Roo on K9 Yeast Defense and within days, he no longer had that awful smell." - The Davis Family, California

    Why Is K9 Yeast Defense Sold As A Package With Power Probiotic?

    While you can purchase K9 Yeast Defense on its own, to achieve the most favorable results, it's important to combine it with the best probiotic for dog yeast infections: Power Probiotic. Simply eliminating yeast without replenishing the beneficial bacteria won't be as effective.

    Power Probiotic contains the best probiotics for dogs with yeast. Power Probiotic is a multi-strain probiotic supplement that promotes the growth of friendly bacteria. Contains 6 powerful strains along with prebiotics to increase absorption and survival of the bacteria. Made in the USA under strict GMP standards, Power Probiotic is 3rd party tested and certified. Using Power Probiotic is essential if your dog has taken steroids or antibiotics, as these medications reduce the population of friendly bacteria. Easy and convenient to use, Power Probiotic can be in and out of refrigeration without decreasing effectiveness. This makes it perfect for travel. Pure, safe and natural - most pets love the taste of Power Probiotic.

    What To Feed When A Dog Has A Yeast Infection?

    Dog itchy and smelly skin, or an increase in your dog licking paws and groin, is due to itchiness and irritation from the INSIDE. A yeast infection in dogs can present as an inflammatory skin condition. While topical lotions and shampoos will help to treat sores and skin infections, in order to stop the need to lick and chew, you must control the itching and discomfort that is causing the problem in the first place.

    What creates yeast overgrowth and a dog’s need to lick constantly? First and foremost, allergies — both food and environmental. Also, the type of food — too many carbohydrates, even in a "hypoallergenic" diet, can cause yeast overgrowth. The first step in any dog yeast infection treatment is to change your dog's diet. A dog with a yeast infection should be on a healthy hypoallergenic diet that is low in carbohydrates. Ask Ariel has helped clients achieve exceptional results with their dogs’ chronic yeast infections, so be sure to include what you are feeding your dog on the order form at checkout. We will review your pet's information and include a free diet suggestion on the packing slip that comes with your order.

    Product FAQs
    K9 Yeast Defense Frequently Asked Questions (FAQs)

    Why does my dog constantly lick its paws?

    Yeast overgrowth is more common in dogs with allergies. When allergies and yeast overgrowth are combined, they can cause doggie odor, constant licking at the paws and genital area, scooting and ear infections. K9 Yeast Defense is an all-natural herbal remedy that kills off the yeast overgrowth to help stop the itching and constant licking. One of the best dog licking paws remedies is a combination of K9 Yeast Defense and our AllerEaze supplement. K9 Yeast Defense works best when used in conjunction with AllerEaze to help relieve the allergic response.

    Why does my dog smell yeasty?

    Allergies, hormonal imbalances, fungi and parasites can lead to yeast overgrowth on your dog’s skin. This often results in an unpleasant cheesy smell. Topical sprays and shampoos may temporarily mask the odor, but the candida yeast needs to be treated from the inside out. K9 Yeast Defense, when used in conjunction with Power Probiotic and diet changes, will help rebalance your pet's intestinal flora. The addition of a powerful and effective probiotic helps to avoid the risk of your pet developing a bacterial infection while you are killing off the yeast.

    Can coconut oil treat a yeast infection in dogs?

    Caprylic acid is derived from coconut oil. It is a naturally occurring fatty acid that has been proven to be an effective antifungal compound that kills candida yeast. K9 Yeast Defense combines caprylic acid with pau d’arco and oregano oil to optimize its antifungal and immune-boosting properties. Pau d’arco and oregano are herbs that have been widely researched for their antimicrobial and antifungal properties.

    How do dogs get yeast ear infections?

    Ear infections are a common canine health problem, and they can be caused by allergies, yeast, ear mites or bacteria. Fungal yeast organisms are normally on the skin and in the ears. If the ear or ear canal becomes inflamed, the yeast can overgrow and create a distinctive blackish oozing discharge and a pungent odor. Your dog may also display head shaking, redness or excessive scratching of the ear. The combination of K9 Yeast Defense, Power Probiotic and NotaSAN is an excellent dog ear yeast infection home remedy to help prevent and control chronic ear infections and odor.

    What causes a dog to get a yeast infection?

    A healthy balance of good bacteria and other microorganisms in your dog's microbiome (the ecosystem of microorganisms in your dog's gut) is vital for your pet's health. The microorganisms in your dog's microbiome form a protective barrier in your dog's intestinal tract that can protect it from harmful invaders such as bad bacteria (e.g., E. coli), fungi (yeast) and viruses. Sugar (found in starchy carbohydrate dog foods and treats) feeds these pathogens, while antibiotics and steroids can kill off your dog's friendly bacteria, thus weakening your dog's immune system. This can set up an opportunity for yeast, bad bacteria and other pathogens to overgrow. When yeast overgrowth occurs, symptoms such as constant licking and scratching, smelly ears, hot spots and itchy paws occur. Yeast thrives in warm, moist environments and is most common in the armpits, groin and ears and between the toes. Skin yeast infections are generally caused by a high-carbohydrate diet, allergies or antibiotic use. All these factors can lead to your dog’s itchy and smelly skin. By using K9 Yeast Defense with Power Probiotic and the best diet for yeast infections, you can give your dog natural, effective relief from yeast infections.
