I feed the raw and I use different kinds of kibble, too. I use them far enough apart to not cause problems. (hopefully) My dogs LOVE the raw diet.
Their favorites are the beef and chicken. I buy it in the patties cause I have more dogs to feed, but if you just have one or two, the medallions are very convenient and easy. The patties are cheaper in the long run when you're feeding more dogs.
The dog I got when she was six months old has been eating this since she was a pup - she is 19 months now.
