All Redbarn Bones are purchased from USDA (United States Department of Agriculture) approved slaughter houses. Once received, we clean, dry and cook them. Nothing is added during this process that would compromise or alter the natural properties of the bone. Any Natural bone can splinter or break and for this reason we recommend supervision when feeding any treat as a precautionary measure. Please keep in mind that not all treats are suitable for all breeds.
