I feed my dogs raw food because we didn't have good foods available here until recently. Now, we have Acana and Orijen available. While we are staying on raw food for their dinner, I want to put them on kibble for breakfast. I want to do this for the following reasons: I feel the variety will do them good, I think they need the kibble to clean their teeth, they enjoy eating kibble (we tried an Orijen sample) and it's more convenient for me in the morning.

I know that Orijen is grain-free and Acana not, but which is better for Yorkies? I think someone mentioned before that Yorkies do better on food with grain... Can anyone help me out?
