High protein is not necessarily bad for kidneys, as there is plenty of research out there showing the opposite. So don’t ward off higher protein foods, whether that be kibble or raw or whatever. Remember… all dogs are different, just like you and I. What works for one doesn’t necessarily work for another, and vice versa.
Without seeing the exact foods you fed, not just the brand of foods, I unfortunately can’t make solid recommendations. But it sounds like you’ve gone through enough, so perhaps just going with home made would be ideal. There’s a forum here for raw diets, which gives a number of recipes. So check that out, as it’s important that you give your pup a balanced diet. I know that doing homemade incorrectly can lead to many problems.
