Thanks for reaching out to us. We're sorry to hear about your dog's experience eating the Waggin' Train Limited Ingredient, Grain Free Dog Treat, Chicken Jerky Tenders. Your feedback is extremely important to us, and this is not the kind of experience we want him to have. Making safe, healthy, and nutritious food for other people’s pets, as well as our own, is a responsibility we take very seriously. Additionally, we'd like to gather additional information to learn more about this and further assist you. Please give us a call at 1-800-778-7462 (800-7PURINA). We're available Monday through Saturday from 8 a.m. to 5 p.m. CST, and we look forward to speaking with you - The Waggin' Train Team
