Primal Recreational Bones are 100% human-grade, antibiotic and steroid free without added hormones. Our Recreational Bones are procured from ranches in the United States. Dogs 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. Recreational bones offer an excellent method for dogs to exercise their jaws, massage their gums and clean their teeth while consuming amino and essential fatty acids that promote a superior quality of health. Primal Pet Foods carries a full line of recreational bones for dogs to have as a treat to enhance their tooth, gum and jaw health. Primal recreational bones are NOT to be completely consumed and should always be fed under the supervision of a human being.
