The best health for a kibble-fed dog IS to be on a rotation of proteins and brands of foods; it's becoming a huge recommendation now to NOT feed the same brand or protein of food for months at a time, let-alone for the life of the dog.
The only way to know is to try it; I have one dog that didn't do good on kibble of any kind, extruded or baked; and is utterly thriving on a raw diet. Of which I know is not for everyone; but it did cure all of his digestive/butt issues
