What's important to remember is that while dogs have many unique physiological aspects to their chemistry, they also have many that are similar to humans. And the subject of *yeast* happens to be one of those. Candida albicans (a common yeast) is opportunistic in both dogs and humans. What this means is that it's naturally present in the body, but is kept in check by the body's pH level, healthy bacteria residing inside the intestinal tract, a healthy diet and the body's immune system. When the body is out-of-balance, the yeast spores are allowed to multiple in larger numbers and create a condition known as Candidiasis (commonly called a yeast infection). This, in turn, causes a host of many unwanted symptoms.
To help eliminate a yeast infection the primary focus needs to be diet. For dogs (if possible) you will want to use a raw or whole foods diet and make sure that the food contains no sugar and little or no starch (grains), which turn into sugar during the digestive process ... these ingredients only work to feed yeast and are unnecessary in a dog's diet. Their are many different brands of high-quality dog food now available through online sources at affordable pricing. In addition, it's very helpful to give your dog a probiotic supplement. Probiotics are simply *healthy* bacteria and when these colonies have high numbers, they naturally discourage bad bacteria from growing. The reason it's a positive step to implement the use of a probiotic supplement is that when high numbers of unhealthy microbes (like Candida albicans) are present inside the body, they release acids that kill off healthy bacteria, so it's important to work to reestablish the probiotic atmosphere through supplementation. Several considerations with Probiotic use: 1) Quality is VITAL! You must have a stable product that contains high enough numbers of healthy bacteria for the supplement to work. 2) Handling. You need to purchase from a company that knows how to properly handle and store probiotic supplements. They are sensitive to heat and light and you don't want to pay good money for a useless supplement. 3) Probiotics should be taken with little or no food. This is because the stomachs acids can damage the healthy bacteria. Since you want them to end up inside the intestinal tract, you don't want them sitting in your pet's stomach waiting for their food to digest.
Next is a quality digestive enzyme. Since Candidiasis can impair the absorption of nutrients, supplementing with a digestive enzyme will help improve your pets health by helping them get the most nutrition from the food they're eating.
