I'm not sure if I'm ready to take the plunge into feeding raw food all the time. But, I'm interested in giving my dogs raw bones because I heard it's good for keeping their teeth clean. Where do you get bones? Grocery store? Butcher? Pet store? And which bones are good? Which are bad? I thought that chicken bones are bad because they splinter but, I noticed from reading post that many of your dogs are eating them. Is it only the cooked bones that splinter?
