If you haven’t been through the DFA Library yet, there are some helpful articles there about how to choose dog food, ingredients, ingredient labels, canine nutrition, etc.

For me personally, I chose 1) a small kibble, 2) generally not less than 30% protein for kibble, 3) gluten free, 4) not less than 36% protein dry matter for wet food, 5) no by-products/sugar/food color/BHA/BHT/ethoxyquin/sodium nitrite, and I generally do not buy from the large corporations (the ones that also make candy bars and toothpaste and other household items).
Also, I feel diet variety and rotation is important so pick various proteins and types of foods (raw, canned, frozen, dehydrated/freeze dried, kibble).
