These chews are phenomenal- actually kept my pup occupied for an ample amount of time, most “busy bones” aren’t worth their weight. This chew not only kept my dogs short attention span focused on one thing, it took him at least half a day to finish one chew. (With breaks of course). The chew didn’t make his gums bleed at all or seem to upset his stomach and he seemed to thoroughly enjoy it until the end; not get bored with it like some dogs do when most bones tend to lose their flavor after a while. Great purchase. Definitely should have bought a larger stock. Will be purchasing more.
