Oh Sacha, I am so sorry to hear about Kamahi's flare ups. I have no help for you, I was the one who recommended the Solid Gold Wolf King. The only other thing that worked for me with Lakota was Home cooked Oatmeal and boiled, rinse and drained ground beef. I am sure that wasn't balanced either, but I only used when recovering from a flare.
Not sure if you have read this yet. Low Fat Diets in the Whole Dog Journal.https://www.whole-dog-journal.com/issues/11_12/features/Healthy-Low-Fat-Dog-Foods_16088-1.html
I fed Royal Canine GSD for a while, I would maybe give this a try.https://www.royalcanin.com/products/roya...y-dog-food/3932
