Look for a food where the first ingredient is a recognizable meat or meat meal (Chicken, Lamb meal etc) and avoid foods with corn, any byproducts, and artificial colors and flavors. Remember that ingredients are listed in order by weight, so if there are blueberries listed after salt, they really don’t count!
