I just bought the Busy Buddy toy that had chewy rings on either side of the ball in the middle which I thought was a great idea! My puppy LOVED it! The toy was $20 and the chewy ring refills were $10. Well, it caused pretty bad stool problems and both are made in china which I've found to be bad after reading all the food warnings here at DK. I threw both in the trash and my puppy is looking all over the house for it. :)
So much to learn about commercial pet food and treats.....ugh! Beware!
