Instinct is their GRAIN-FREE kibble.. (which we leave down, just in case the girls get hungry) but we primarily feed NV raw medallions, instinct canned, ziwi peak cuisine & canned, the honest kitchen, & rotate other RAW foods, randomly, as well!
Nature's Variety is a good food.. and if you are wanting to feed a kibble that does have grains, i would feel comfortable with their prarie line!
either NV prarie or Innova.
now if you want a grain-free kibble, you should look into the NV instinct kibble:
