Nope, my boys have never gotten sick from raw. Our vet was very helpful when I was learning about feeding raw. He never told me to feed one thing or the other, he only gave me his experiences.. no opinions. He told me that in all his years of being a vet, he has never seen a single dog get sick or injured from the raw diet. He has seen countless cases of dogs that got cooked bones and were injured, but never raw. Of course, it'll happen with raw.. but whenever I hear mishaps with the raw diet, I always find out the dog was being fed an inappropriate sized RMB.
