Thanks for reaching out to us. We're sorry to hear about your GSD's experience eating the Waggin' Train All-Natural High Protein Chicken Jerky Dog Treats. Your feedback is extremely important to us, and this is not the kind of experience we want them 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. We'd like to gather additional information to learn more and further assist you. Please give us a call at 1-800-778-7462 (800-7PURINA). We're available Monday through Friday, 8 a.m. to 6 p.m. (CT), and Saturday through Sunday, 8 a.m. to 5 p.m. (CT), and we look forward to speaking with you. - The Waggin' Train Team
