What is a Systemic Yeast Infection in Dogs?
Yeast Candida and Fungal Skin Issues in Dogs (or Cats)
Early symptoms of Yeast (Candida) taking control of the Gut are not so obvious; it’s mostly about itching/scratching, and too much licking at feet or legs (maybe some chewing involved). If things are allowed to advance over months, and contributory foods/treats are in the diet, then things can get ‘out of hand’ pretty quickly – and even quicker if typical veterinary “treatments” get involved (steroids + antibiotics). Minor ear infections are a possibility at these early stages – some itching, shaking of head, and minor inflammation with ear. As the systemic yeast infection symptoms worsen, things will usually become pretty obvious: itchy red or blackened skin, hot spots, offensive odor, ear infections, or raw itchy paws. But what exactly is a systemic yeast infection? To gather a much deeper understanding of how the Candida yeast – while taking control of the Gut – manages to ravage the body, and create havoc everywhere, we provide a very short but helpful Video that sheds light on the issue, although from the Human point of view. Since we’re all about pet health, that is where we keep our focus; and, we have tremendous success in this area, though solving these issues is not easy.
As inferred above, this page is a short ‘overview’ on this demonstrative health issue. If you care to really learn – at an ‘in depth’ level – we suggest you jump right over to our LEGACY YEAST INFECTION ARTICLE.
Simply put, a systemic Yeast Infection in dogs is the results of an imbalance in the GI (gastro-intestinal) tract – the gut. In the gut, naturally, there are billions of beneficial bacterial flora colonies, and fungal residents as well such as candida yeast. When all is well, each produces by-products that benefit each other. However, when something comes along to upset that balance, this is when troubles begin – allowing ‘opportunistic yeast’ to begin to take over, with the possible result of serious Yeast infection areas taking over intestinal walls (see photo).
The purpose of the good bacteria is to function as a protective lining of the GI tract, creating a natural barrier and aiding in the digestive process. This balance helps insure a strong, sound immune system and better general health.
Unfortunately there are many things that disrupt the good bacteria and the body’s natural balance. The most problematic are the using of antibiotics and steroids which disrupt the natural balance while fighting infection or inflammation. Pet foods and treats that use sugar-dominant ingredients are the worst, but there is also preservatives, additives and colorings in our dog’s food that affect these changes. Sometimes simple stress can be a culprit.
Any or all of these factors can cause the protective flora within the gut to diminish. As this protective barrier disappears, the far less delicate and always opportunistic yeast will begin to expand and take over those spaces formerly occupied by the friendly bacteria.
This is what is known as a yeast overgrowth. In time, the by-products created by the yeast overwhelm the local environment, and are carried by the bloodstream to the surface for filtration. These toxins then exit through the paths of least resistance – hair follicles and skin cells (especially in the ears and on paw pads). The problem is already a deep problem by the time we notice the itchy or blackening skin, hair loss, hot spots or reoccurring ear infections. And these symptoms are often diagnosed as allergies – treated with antibiotics or steroids, which further weaken the already over-run immune system and only suppress the symptoms… without dealing with the internal problem at all. But allergies is a diagnosis that “seems” to make sense – on the surface.
Once the protective flora of the gut has been eroded, inflammation begins to take place as the yeast takes over. This causes the cells of the intestinal lining to become enlarged and porous so that foodstuffs gets stuck. These bits of undigested material then enter the bloodstream and leech onto and into other tissue creating an immune response that usually results in a false positive allergy test. Instead of allergies, this condition is actually referred to as leaky gut syndrome. If left untreated – or treated as allergies – this condition often becomes worse as the yeast digs deeper roots, further damaging the intestinal wall.
What makes this problem worse?
As mentioned above, common food ingredients and medications are the big offenders. Let’s start with your dog’s food.
Yeast as an organism, is fed by sugars and starches. Start by checking the ingredient list on the food you’re feeding. White rice, corn, wheat, potatoes, sweet potatoes and tapioca should always be avoided as a primary ingredient on your dog’s menu (especially if you suspect a yeast problem). Primary ingredients are the ones listed first in the (usually long) paragraph of edibles on the back of your kibble bag. These ingredients, like corn and potatoes, are simple starches – and simpler the starch, the faster it converts to sugar in the body. The faster in converts to sugar, the more it feeds the yeast, making it grow.
Medications like antibiotics, steroids, antihistamines or other immune suppressants also aggravate the delicate balance in a dog’s gut. These drugs may help suppress symptoms, but only by turning off the immune system’s natural function.
Think of the immune system like a muscle. When it’s working, being used and being nourished, it grows stronger. If it’s shut down (much like a leg in a cast) it shrinks and grows weaker. When the drugs are stopped (or the cast comes off), it takes focused attention and extra effort to recondition this muscle back to its normal, healthy purpose.
Perhaps you’ve heard the saying, “all good things in moderation”… and that is exactly the point with yeast. Yeast is a good thing – in moderation. Kept in balance, it is part of a dog’s healthy, happy inner harmony. But if it’s given opportunity, yeast will over-grow, and present a very formidable challenge to overcome. The good news is, once you understand what is it that you are battling, you can take action to correct it.
