Hi Joseph,

The amount of carbs, grains, sugars, etc in the diet have nothing to do with yeast growth on skin. If your dog has a food hypersensitivity reaction (allergy) to an ingredient in the diet the adverse reaction can alter the skin and allow yeast to grow.

You can find good information about yeast on skin here http://www.healthyskin4dogs.com/blog/2015/9/8/facts-myths-about-yeast-dermatitis-in-dogs
