You should try grain, corn, white potato, brewers yeast and rice free. Also avoid foods containing tomatoes, soy, probably all forms of poultry also. Night shade plants, some of which are tomatoes and potatoes, are high histamine foods. I agree with Marie and the Natures Logic food. Natures Logic has a sardine kibble that may work for you. Just go on the review side and check out grain free foods and then check out the four and five star reviewed foods. Anyway, hope your dogs get relief. Until I eliminated the ingredients I mentioned my dogs ears (all three) were always yeasty and smelled. I was constantly cleaning gunk out of their ears.
