Ah, darnit, I finally found a chew that Izzy can't destroy in minutes and I *think* it upset her tummy. I probably let her have it too long, she was able to chew off quite a bit of it before I noticed and took it away. She had loose stools the day after getting the new chewies. Gave her pumpkin and it firmed right back up again.
So now I'm wondering if I shouldn't let her have those anymore

How about Antlerz? Anyone have any reviews on those?
