I've never used that variety of California Natural food, but I did read up on it the other day, actually, when I was looking for cat food for my cat, who has some skin issues. Perhaps using the CF Natural or Innova treats would be the way to go. I have to "forewarn" my supplier if I need the CN foods, but he has access to all of them.

I can't imagine why it would hurt to have both dogs on that food. It can't hurt to try, at least!

Good luck, Heather.
