I think that kibble is probably best for yorkies because it helps keep their teeth clean and helps with the common dental problems that yorkies have. I mean, Royal Canin for yorkies has specially constructed kibble to help clean their teeth. I would see if you can find anything that talks about dental problems in relation to a holistic diet in small breeds and read about what they say! Also, talk to our vet. I bet he would have good advice on it!
