Can anyone suggest a top of the line kibble that is fish based? Also, what is the benefit of grain free kibble? My Shiba Inu has had skin allergies, ear infections, and stomach distress in the past. He has been on Kirkland Chicken, only one big bag, because his stool was always soft. Wellness chicken super5 kibble. And Innova adult chicken kibble. I think he would benefit from fish in his diet, because that is what his ancestors ate.
