Thank you for choosing Dog Chow. We're sorry to learn that your dogs didn't enjoy Purina Dog Chow Complete Adult Dry Dog Food, Chicken Flavor. Please know that they are attracted to their food by the way it tastes, smells, and feels in their mouths which might explain why your pet is not eating the new food. We recommend consumers introduce a new food over 7 – 10 days to help avoid refusal-to-eat situations. We want to gather more information about their preferences and help you about the food they might love. Please contact us with this link: https://www.purina.com/contact-us. - The Dog Chow Team
