Back when I was still feeding kibble occasionally NOW! grain-free was one of my favs - and I rotated through a lot of the 'higher' quality brands but seemed to have the best results with rotating and occasionally mixing NOW! grain-free, Fromm's grain free, and one of the Acana all life stages grain-free formulas. If I for some reason had to feed my dogs kibble again, it would definitely be one of those three.
