I think Katrina starts feeding her pups RAW pretty much as soon as they're weaned... hopefully she can help get you started.
If it was me, I'd start w/one food source (probably either ground or cut-up chicken), nothing else during the first week, just add a supplement (like Nupro, for instance). I would gradually add other things afterwards, just to make sure that the puppy tolerates the switch well. Treats in moderation.
Are you getting a new puppy???
