FITS THE LARGE SIZE BUSY BUDDY JACK FOR LARGE DOGS
Our Busy Buddy jack is the large size for our Great Pyrenees. He loves it when I refill with the "C" size rings. Great for him to chew on. Finally subscribed to reorders to we don't run out.

Worth the money
This is a better way to buy the Busy Buddy replacements. You get 2 flavors in one package. With my picky pups, I never know which one they want so two flavors help with that!
