Hi Joseph,
I have no doubt that you could post link after link claiming that the carbohydrate level in the diet influences yeast growth on the skin, but none of your links would be to articles authored by board certified veterinary dermatologists, human dermatologists or be from published peer reviewed journals. The reason for that is because there is no link between dietary carbohydrate levels and yeast infection on the skin in people or dogs. There is a lot of misinformation on the web and unfortunately some of it is spread by people who should know better.
I understand that testimonials are compelling, bloodletting used to be the cutting edge of medicine based on the observation that “it worked”. But things that appear to work, when tested can be found not only not “to work” but to cause harm.
You came here asking for help because what you have been doing isn’t working. Be open to new information that takes you in a different direction. Malassezia is secondary to things like environmental allergies, adverse food reactions (allergy), hormonal disorders, immune suppression, parasites… focus on finding and treating the primary cause. In the mean time bathing with an effective shampoo can help your pet immensely.
Best Wishes
