I guess everyone will think I'm a terrible pet owner but I've been giving Cody a 4in rawhide bone for years. I gave him one as a treat years ago and he goes crazy if he doesn't get one every night-he actually goes to where I keep them and sits. He doesn't always finish it but sleeps next to it and carries it around. I promptly toss it when he drops it, but he has NEVER choked on one and I also keep an eye on him and toss the mushy pieces he drops. He HAS to be in our den while we watch tv, so luckily someone is always there, but now I'm really worried and hope my luck doesn't run out. It's time to try a substitute. He's so habitual, it's gonna be a hard habit to break.
