Blue Buffalo Wilderness Rocky Mountain Recipe with Red Meat Large Breed Grain-Free Dry Dog Food is hot extruded (which means it's processed under extreme heat and pressure) and made with feed grade ingredients, which are unfit for human consumption. It contains 27 synthetic additives (so it is not all-natural), it has 9 anti-nutrients including Tapioca Starch, Peas, and Pea Starch (which may interfere with the absorption of essential nutrients), and it has 1 other sketchy ingredient, Vegetable Juice for color.

Warning: In June 2019, the FDA implicated Blue Buffalo's dog food in at least 10 cases of Dilated Cardiomyopathy (or DCM), a potentially fatal heart condition.
