Autumn gets rawhides because they grind down with the teeth, I've never seen a rawhide fall into little chunks, except the very end pieces. I don't give her greenies because they stain things and they are expensive. I'm not afraid of greenies though. I watch my dogs. Pepper has choked on cow hooves and rawhides but we were there to take them away. Autumn can't have meaty bones because she gets big chunks off of them. She can't chew on kong toys either because she gets pieces off too. I won't give bully sticks or ears because of the smell and I'd assume they can choke on them just as well.
