One of the things I've continuously heard about the bacteria issue is that dogs don't keep food in their system for very long, so, supposedly bacteria doesn't have time to just sit around and cause problems. It's passed relatively swiftly, unlike humans. And, I didn't hear that about raw bones not splintering....hmmm... it's the one thing I'm not comfortable with. I've done a lot of reading, too, and, one of the things (supposedly) that kills wild dogs is splintered bones. I've been able to get past all my old preconceptions about diets for pets, except for the bone thing. I am cool with beef bones, but, the fowl bones just seem to be unsafe (although I know plenty of people that feed them and their dogs are fine). Anyway, I'm still looking for the sites I got some info from.
