Keep your dog entertained with Pet Qwerks BBQ BarkBones . Made for aggressive chewers; these durable dog chews are proudly made in the USA with pure nylon and BBQ essence that are blended to create the most durable; safe; and tasty dog chew bones. BarkBones have a curve that helps make it easier for dogs to pick up and carry with their mouths. The patented molding process means no two bones are identical and have a natural realistic look.PRECAUTION: Don't be surprised if your dog creates granules of nylon while chewing. These little rice size bits are usually not swallowed; but if they are; they'll pass without a problem. For a satisfying chew experience; your dog should be able to do some damage to the chew. The texture should be scratchable; not glass-hard. It is important that you always monitor your dog when new toys or chews are introduced. While these are extremely durable; no dog toy is truly indestructible. If your dog happens to break pieces off; immediately remove the chew from being chewed on.
