Dietary Recommendations for Treating a Dog's Yeast Infection?

We have a 10 pound Maltipoo puppy and we feed her Holistic Select which is wheat, soy, color, and preservative free. I am wondering if that is good enough. I have read that raw meat is better, but I wouldn't know how much or what kind to feed her. Any food ideas? Thank you for your help! and thanks to this web site I am treating Sugar naturally for ear fungus. Thank you!
