Wiley's Chicken Snaps are made from raw materials sourced from local Northern California farms that practice humane and sustainable agriculture. Our chickens are raised on a vegetarian diet that is hormone and antibiotic free. We lightly process and dehydrate these healthy chicken hearts and gizzards to create Wiley's Chicken Snaps. They are great for training and were developed to inspire dogs to do what you tell the . . . the first time!
