I'm still researching! I haven't been able to find anything yet on soy (good or bad), so, if anyone has any links I can check out, please post them. As for eggs, I'm finding a lot of sites are recommending egg shell powder for calcium. Any comments on that? One site recommended 3 teaspoons per pound of meat. Doubled for puppies. And, I keep running into sites saying fowl bones are dangerous, even though I've heard several comments here that they are fed. I'm not saying I believe one more than the other, but, I would like some feedback on feeding, for example, turkey necks or chicken backs. It does seem like they would splinter, I know personally, I have had a bad experience with chicken bones. But, I don't know, it's why I'm asking. I'm all for giving raw bones, but, I'm leaning towards beef bones from the meat shop for the dog to chew, but, as far as a puppy is concerned, would it be better to serve ground bones? I just don't see how a puppy could really EAT bones....chew, yes, but, do they really eat the bones? I think I'm taking a break from the research, it's overwhelming! I have a few questions for my vet when I see her next, but, I wanted some opinions from here, too!
