Hi Brenda,
The homemade diet you are proposing is very unbalanced. Also diet is very rarely involved in the causation or treatment of yeast infection of the skin so a diet change is very often not needed. Unfortunately there is a common misunderstanding regarding diet and yeast. Lower carb diets have been recommended to control symptoms of Candida yeast overgrowth in the intestine of people. This information has been misapplied to the treatment of a dog’s yeast infection, but the yeast infection of the dog’s skin is completely different problem. The yeast itself is different. Yeast in the human intestines is usually, Candida a carbohydrate loving yeast. The yeast on a dog’s skin is nearly always Malassezia which is a fat loving yeast. An oatmeal shampoo won’t specifically address yeast but it won’t feed them either.
Here is an article that addresses treatment of yeast infections in dogs http://www.itchnot.com/images/Malassezia_Dermatitis.pdf
