The Association of American Feed Control Officials (AAFCO) has developed certain minimum guidelines for best dry dog foods and recommends that for the foods to be considered natural, they should not have artificial preservatives, colors, or flavors. Labels that advertise organic dog food should generally refer to the way the products that go into the food have been grown or raised. In a quest to find the best dry dog food, some pet owners may turn to brands that advertise "natural" or "organic" ingredients.

The vegan option for their best dry dog food includes brown rice, oatmeal, potatoes, and green peas. This dry food product is made with organic brown rice, peas, and carrots — and skips the added hormones, antibiotics, or chemicals.
