My giant dogs go through almost any chew toy in seconds. We decided to try the Busy Buddy bones with the treat rings that can be replaced after the dogs decimate the treats. We love the rings and have them set up for auto delivery. I find that it gives my pups a solid hour of chewing time and mental stimulation as they try to get the ring off of the Busy Buddy toy. One of my dogs has a sensitive stomach - and we have no issues at all with peanut flavored rings. Highly recommend.

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!
