Nulo Challenger Organic Ancient Grains Beef, Lamb & Pork Recipe names four animal proteins in its first six ingredients: deboned beef, deboned lamb, salmon meal and turkey meal, followed by deboned pork and chicken meal. At 35.0 percent minimum crude protein as fed, it is the highest protein recipe in this file. The Challenger line pairs organic grains, here organic oats, barley and millet, with the ancient grains format the manufacturer also uses in Frontrunner. The manufacturer's own AAFCO statement calls the recipe Alpine Ranch Beef, Lamb & Pork, a name not printed on the product title itself. It is formulated for all life stages except growth of large size dogs, and sold in 4.5, 11 and 24 pound bags. Dogs who lose interest in a rotation often take it again with a single ingredient freeze dried topper crumbled over the top.
