Hi Jannie,
You have touched on the reason I quit giving bones to my dogs...too many arguments on both sides and I felt that bone fragments harming them was too much of a risk for me...although, I sometimes rethink my position when I see how healthy the raw fed pups are!
I think that you will have danger in either types of diet. My dogs loved raw...and they don't eat well on kibble, they hate it...so I am always wondering which way to go.
I have heard that raw bones will digest, where cooked bones won't. How true that is, I don't know.
I did the research, as you have, and can't find a good answer.
But, again, I know people who even feed tiny puppies on a raw diet, including chicken wings! And they are extremely healthy.
The deciding factor for me was when I read experts talking about the reason that bone fragments don't bother wolves is that they also eat skin and fur and the fur wraps around the bone...when they look at their excriment, they find that the bone fragments are wrapped in fur!
Some raw feeders do feed fur/feathers and all...don't think I could go that far!
