Merrick Grain-Free Real Buffalo 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 19 synthetic additives (so it is not all-natural), it has 7 anti-nutrients including Sweet Potatoes, Potatoes, and Peas (which may interfere with the absorption of essential nutrients), and it has 1 other sketchy ingredient, Natural Flavor.

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