Angus & Roxey have never liked the nyla-bones, now I'm glad! And once I gave Roxey and Angus a bone, it was kinda crunchy and was supposed to have carrots & such in it, maby that is the one you are thinking of Melissa, I'm not sure, but I gave them one ONCE and that was it, it gave them both the runs! But they did really like it! I guess too much veggies or something?
