What is K9 Yeast Defense?

K9 Yeast Defense is a natural blend of antifungal herbal ingredients scientifically proven to keep your dog's yeast under control. Yeast is a natural part of our intestinal flora that keeps other bacteria and parasites in balance. However, antibiotic use, allergies, poor digestion and a diet high in starchy carbohydrates can lead to a chronic yeast overgrowth. This leads to the common symptoms of yeast such as licking at the groin, chronic ear infections, doggie odor (even after a bath), ear scratching, yeasty smell on the paws and skin problems. Yeast is typically a "secondary invader" meaning that bad bacteria is usually first to arrive, along with the yeast. Using the K9 Yeast Defense along with Power Probiotic and NotaSAN can control the yeast, replenish with friendly bacteria and rebalance intestinal bacteria improving symptoms and your pet's overall immune system.

It's essential to use the Power Probiotic along with the The K9 Yeast Defense as the K9 Yeast Defense kills off the yeast overgrowth quickly, while the Power Probiotic replenishes your pet's gastrointestinal tract with good bacteria which are needed to restore your dog's healthy immune function. Power Probiotic is the best probiotic for dogs with yeast infections.

Symptoms of Yeast Infections in Dogs

What are the symptoms of yeast overgrowth in dogs? Typically dogs have chronic skin infections, redness, chewing on paws, dog yeast infection on the paws, doggie odor, chronic ear infections, genital licking and/or have been diagnosed with yeast infections in between the toes, groin, ears or under armpits. Dogs will lick and lick creating a smelly, moist hot spot making it impossible for the areas to heal and dry out. If your veterinarian has ever diagnosed yeast before or your pet has taken prednisone and/or antibiotics, this will lead to yeast overgrowth because the good bacteria which fight yeast are killed by the medications. That is why your veterinarian might prescribe a prescription medication for yeast at the same time as an antibiotic.

  • Dog Skin Yeast Infections
    • Constant licking and scratching
    • Foul odor even after bathing the dog
    • Discoloration/darkening of the skin and fur
    • Redness of the skin
    • Chewing on paws

  • Yeast Infections in Dogs Ears
    • Scratching at ears
    • Tilting their head
    • Wax residue and/or scabbing at the ear opening

Relieves Itching and Irritation From the Inside

Put an end to your dog's licking, chronic ear infections, doggie odor and chewing at the groin once and for all. With the K9 Yeast Defense Package you'll get two great products in one - K9 Yeast Defense + the Power Probiotic. Both products are veterinary-approved for controlling yeast overgrowth and controlling dog yeast infection symptoms.

Dog licking is due to itchiness and irritation from the INSIDE. 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 licking in the first place. What creates yeast overgrowth and a dogs licking 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. A history of taking antibiotics or steroids will also create a friendly environment for yeast to grow, promoting your dog to lick and lick.

To stop your dog's constant licking, you need to change the diet AND use the K9 Yeast Defense Package.

K9 Yeast Defense + Power Probiotic + NotaSAN (capsules or drops depending upon your dog's size)

Please order the
NotaSAN separately along with K9 Yeast Defense + Power Probiotic.

NotaSAN fights bacterial infections. This is very important when using any yeast detoxification formula, but especially if your dog is just finishing antibiotics. If you just use K9 Yeast Defense and Power Probiotic, without NotaSAN, there is a possibility that as the yeast dies off, your dog may get a bacterial infection. Using all three products in combination is the best way to ensure your dog will not getting a recurring bacterial or yeast infection. The NotaSAN helps relieve the symptoms associated with yeast die-off.

Why Is K9 Yeast Defense sold as a package with Power Probiotic?

In your pet's best interest, K9 Yeast Defense must be used properly and safely to help rebalance your pet's intestinal flora. We require that the K9 Yeast Defense is used with a powerful and effective probiotic. This helps to avoid the risk of your pet developing a bacterial infection while you are killing off the yeast. If your pet has had any type of yeast infection, ear infection, skin problems or allergies, by far the BEST results occur when the K9 Yeast Defense is used along with BOTH Power Probiotic and NotaSAN which fights bacterial overgrowth.

The Power Probiotic is an easy product to administer and is a powerful multi-strain formula. However, if you prefer to use an alternate probiotic, please indicate the name and dosage of the formula you are using on the order form when purchasing this product. K9 Yeast must be used in conjunction with a probiotic.

K9 Yeast Defense and Power Probiotic are both easy to use--just sprinkle in your pet's food. Please note: Most pets that have yeast have bacterial overgrowth too and have been put on antibiotics only to develop yeast. If you just use the K9 Yeast Defense without addressing the bacterial overgrowth, the pet will be out of balance. Using NotaSAN supports your pet's immune health during and after the use of antibiotics and, when combined with the yeast formulas, helps rebalance your pet's entire immune system. It is possible, if you use only antifungals, for the pet to then get a bacterial infection. Please order the Complete Package along with NotaSAN for your pet's well being.

K9 Yeast Defense may be purchased by itself but it is essential to use a powerful, multi-strain probiotic along with the product for best results. Just killing off yeast without replenishing the beneficial bacteria will not be nearly as effective.


“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. And, for his acid reflux, we started using your supplements (Power Probiotic, K9 Digestive Enzymes, Gastro ULC and Soothing Digestive Relief). We used to give him Pepcid, but we have been able to slowly wean him off. 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!"

Help For Dogs With Chronic Yeast Infections and Allergy Symptoms

Some dogs have severe allergies and have been on rounds of antibiotics. While this can create an environment for yeast to thrive, using K9 Yeast will definitely help, but there is still the underlying allergy situation that has to be addressed. Changing the diet is a first step, so please see our articles about food allergies. But, allergies can often be a chronic condition, sometimes seasonal but many times, just part of your pet's genetics. So, while you control the yeast using K9 Yeast Defense and Power Probiotic, you also need to control the dog's immune system and allergic response that is helping the yeast to grow. Fortunately, through years of experience, we have found formulas that can help. First, as mentioned above, it is essential to use NotaSAN OR NotaSAN + QuentaSAN (ideal) to help support your dog's immune system during allergy season (not needed indefinitely). In addition, AllerEaze and/or Proaller and Amazing Omegas are all proven, time-tested products to use to help control allergies, itching, redness, hot spots, chewing, licking, etc. We have tremendous success with our products, even with some of the most discouraging patients. Dogs with chronic yeast and allergies can improve, it just takes a little patience, good products and the right diet.

Yeast Infections in the Ear

Yeast infections in the ear can become a chronic problem for dogs. When a dog has a yeast infection in the ear, dogs may have a distinctive blackish oozing discharge, odor and debris in the ear. Dogs may also display head shaking, redness or excessive scratching of the ear. Dogs can get ear infections from yeast overgrowth, hypothyroidism, food and environmental allergies. Dog ear infections are painful and dogs may have a terrible odor. Left untreated, ear infections can lead to permanent deafness. If you notice your dog displaying any of these symptoms, please take your dog to the veterinarian. Using K9 Yeast Defense, Power Probiotic and NotaSAN can help prevent and control chronic ear infections and odor.
