The Everlasting Treats are long lasting dental chews that are hard like a bone to help keep your dogs teeth clean. Pair them with the Starmark Everlasting Treat toys for challenging chewing fun. Caution: With all chew products and treats, pets should be supervised as no product is completely indestructible. Pieces smaller than the mouth may present a choking hazard. When wet, treats may stain fabric and upholstery.
