I personally know a lady that manufactures BARF.
- she said kibble & raw does not mix daily, with their digestion track
It is one or the other.
Ten or twelve years ago, I was on the raw list that invented this old wives tale when it was being invented (who remembers when rawfeeding was BARF on Smartgroups?). A bunch of people theorizing back and forth about this and that for three or four days, and all at once it somehow got transformed into gospel. There was never any science, there was never even any anecdotal evidence that anything negative would result from combining raw and kibble. It weren't true then, and it ain't true now.
