I had a scary moment years ago with my Whitney (Rainbow Bridge) while she was chewing on a rawhide bone. I also had to stick my fingers down her throat to prevent her from choking on a very slimy piece that had gotten too small. (They are really hard to grab when they are in the back of your dog's throat! I vowed never to get another one, but I weakened a couple of times and got Bella a few and I watched her every minute she had them. She is also a very aggressive chewer and could make them disappear in no time if I allowed it. I have stopped them altogether, though, in favor of more conventional bones. I just don't want to take the chance!
