I have fed pre-made raw (Primal, NV, or Stella&Chewys) for about 3+ yrs now. I really like it for them. Wylie is 7, never had a dental, and his vet loves his teeth. Now, that could be hereditary too...but just thought I'd mention it. I do give lots of chews so the kids work on their teeth....I don't brush (very bad me).
Some here feed Prey Model too, and there are some good threads on this. Oh, btw, there is a thread in the Library on raw too
