I have fed it for years. I stopped for a while, was disappointed w/ the changes as far as adding a bunch of lentils and extra peas and stuff. But honestly? It's what he's always done best on. We more-so feed the Singles variety, and have been rotating the Pork and Duck varieties.
I mostly rotate between Acana and Orijen. We carry those along with some Natural Balance, Taste of the Wild, Nutrisca, and Now at work. When a customer asks for the best kibble we carry, I tell them Orijen and Acana.
I've been feeding the grain free singles in our rotation since we went back to kibble. Great quality like always. Scout particularly does really well on Acana.
