Sorry to hear your graciehad such an ordeal with a toy!; I too had a bad experience with a kong product, which was the cream filler thing you squeeze into the rubber toys for added flavor and interest; I had bought that and the toy just days after getting my baby Chloe, and when I was getting ready to squeeze the cream filler thing into the toy, I realize that even though it was all sealed, it was completely ROTTEN!,

I mean green and black, moldy and completely gross!. Imagine if you're not looking 100% at the substance (as with a new puppy you're constantly looking at THEM). I returned both the toy and the putrid cream thing.
Kong toys are not her favorite at all; her fav. are the petstages which I've tugged at myself, testing how sturdy the stitching is for resistance sake.
I try to give her rope-like toys, and other things that don't have too many sewn pieces, that way I know that if she's messing a lot with them, I can have peace of mind knowing that her playtime item isn't going to become a Nightmare!.
Good luck, I hope she passes it "naturally"....I know the pain of vet bills too!
