From what I read last year on a box of Darford cookies they still have a lot of highly processed carbohydrates in them. I just went to look at their website though and I see they now carry wheat & corn free cookies as well as grain free cookies.
I got to learn something today!
I see their "Zero/G" grain-free kibble as well. It seems to be the only kibble they make (a poultry recipe and a fish recipe). The ingredients
do look good! I don't know much about the nutritional value or metabolic reaction of buckwheat though. I like to see manufacturers trying something different. Please let us know how it goes!
