BarknBig offers the Bison Sailor Bone for small dogs. When we say small, we mean toy breeds that are 15# and under. These sailor bones will float your pup's boat. In the midwest, they call it prairie butter (marrow). It has accessible marrow for nutrition, edges to clean the teeth and flavor to keep them busier than a bull's tail at fly time. This is the ultimate bone for those small dogs that get the short end of the stick when it comes to options for bones to chew on.
