[Hound Dog Mom]

My assumption is one is the old formula and one is the new formula. Orijen recently had a formula change and they may still have some of the old formula in stock or may have not yet updated their website. The old formula contained white potato, the new formula contains legumes instead. Both the old formula and new formula were 75/25 for the Regional Red and 80/20 for the 6 Fish (meat/vegetable).
