Thanks for taking the time to share your concern with us. We're sorry to hear that your dog is not enjoying his or her favorite Purina Moist & Meaty Dog Food, Burger with Cheddar Cheese Flavor, as much as before. Please know that in July 2023, we recently removed the ingredient ‘added color’ from our Moist & Meaty recipes. In addition, we also updated our packaging. While we removed the added color from this product, we would not expect your dog to refuse to eat the new product. Providing high-quality and safe products is our number one priority, and we'd like to learn more and lend a helping hand. When you have a chance, please give us a call at 1-800-778-7462 (800-7PURINA). We are available from 8 a.m. to 5 p.m. (CST) Monday through Saturday. We appreciate your loyalty and look forward to speaking with you. – The Moist & Meaty Team
