Under the Sun Grain-Free Duck Formula Canned 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 19 synthetic additives (so it is not all-natural), it has 3 anti-nutrients including Peas, Sweet Potatoes, and Suncured Alfalfa (which may interfere with the absorption of essential nutrients), and it has 2 other sketchy ingredients, including Cassia Gum and Guar Gum. Many consider this food to be inconvenient, because it requires clean-up.

Warning Due to this being a grain-free food that contains legumes or potatoes this Under the Sun recipe may be implicated in the FDA's ongoing investigation into diet-related Dilated Cardiomyopathy (or DCM), a potentially fatal heart condition.
