The Redbarn Bully Slices for Dogs are made with all-natural cow hide that has been slow roasted to lock in all that delicious flavor. These slices are perfect for treating your dog to a healthy snack or meal. The cranberries, blueberries, vitamin E, and chicken cartilage provide a natural source of glucosamine and chondroitin, which support joint health and muscle mobility. The Redbarn Bully Slices for Dogs are also safe for use on dogs and puppies because they are manufactured in the USA with globally sourced ingredients.
