From the beginning, Puptastic has sourced only the finest Midwestern ingredients: chicken, turkey, lamb, liver, and beef for meat; brown rice and potatoes for starch; and carrots, green beans, pumpkin, and sweet potatoes for fiber and nutrients. Similarly, they’ve always excluded corn, which many customers have enthusiastically noted as one of their top reasons for getting it. Employees thoroughly test everything at the headquarters’ cutting-edge and human-grade kitchens in Grayslake, Illinois to ensure it exceeds the F.D.A.’s and the A.A.F.C.O.’s highest standards; it contains no artificial colors, flavors, or preservatives except a healthy dose of vitamin E that maintains products’ integrity.
