I don't have the knowledge or research to do it just yet. I want to make sure if/when I do, my dogs are getting ALL nutrients needed. But I am also waiting for there to be more research on this diet than is currently available (long term effects, etc). It seems to be a relatively new thing that has recently exploded on the "pet" scene, and I just want to wait until I get everything straight (at least in my mind!) before even attempting, if that makes sense!
