I am still debating whether to attempt to feed twister raw or not. Local store has primal. Being that twister is 24 lbs. not sure if it is economical. Natures variety has a feeding calculator, but still debating. Putting cost aside, do you think raw (nutrition balanced), not grinds, are healthier then say blue buffalo kibble grain free. I have read that Orijen kibble can give some dogs upset stomached. Maybe too rich? I know raw gives far smaller poop.
