Primal Raw Meaty Bones are 100% human-grade, antibiotic and steroid free without added hormones. Our Raw Meaty Bones are procured from ranches in the United States. Dogs and cats have a set of solid molars and extremely strong jaws that enable them to crush and chew raw meaty bones such as necks, backs, wings, ribs and carcasses. Through the consumption of such bones, they are able to acquire an easily assimilated, natural form of calcium essential to skeletal health. These raw meaty bones are for both dogs and cats to have as part of their daily feeding or as a treat to enhance their tooth, gum and jaw health. Raw meaty bones are to be completely consumed. These bones are considered "soft bones" and do not splinter. Primal raw meaty bones should always be fed under the supervision of a human being so as to ensure your pet does not consume these bones too quickly.
