Zignature Whitefish Limited Ingredient Formula 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 20 synthetic additives (so it is not all-natural), it has 4 anti-nutrients including Peas, Chickpeas, and Pea Flour (which may interfere with the absorption of essential nutrients), and it has 1 other sketchy ingredient, Natural Flavors.

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