Anyone have experience with getting rid of a yeast infection in a dogs ears and in his paws?

I've been trying to battle this issue with my 9 year old dog for awhile now. I found a natural ear solution that seems to help, but doesn't get rid of it. Most likely because he's scratches his ears and his paws have the yeast on them..
I've done some research and the diet is the first thing to look at, but I thought feeding him the blue buffalo grain free was good. Now I need to look into a sugar free and wheat free food. Any recommendations?
I want this infection to go away once and for all!

We went through something similar with my last dog, the vet kept telling us that he had allergies but it never seemed to improve. I read a lot about dog food and ingredients, and good diets for dogs. We started using Dogswell Nutrisca (Salmon & ChickPea flavor). Its extremely limited ingredients and doesnt contain potato. I had read that many dogs cant process the high starch vegetables that a lot of foods contain. Its a little pricey but it seemed to help him. Let me know if you have more questions. Good luck! I know it can be very frustrating
