These natural, sterilized beef center bones are cleaned of meat and marrow for a long-lasting chew your dog will love. Each bone is approximately 4 inches in size and proudly made in the USA. Always supervise your pet when offering any chew or treat. ⚠️ Please Note: Animal-based treats may have a natural odor that some find unpleasant and may be greasy, which can stain fabrics or carpets. Never leave your dog unattended with any bone, chew, or treat.
