I don't always think ear problems at this particular time of year are food related. Zoe and Zena have gotten ear problems once in a blue moon...one time since I have had Zena and only once in Zoe's life and both were at this time of year. I didn't change foods. Treated the ear and they never came back. Just a part of spring allergies around here.
You do realize you need to have them on a food 2-3 months; for some dogs even as long as 6 months; before you see results?
