Health Extension Grain-Free Duck Entree 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 18 synthetic additives (so it is not all-natural), it has 1 anti-nutrient, Sweet Potatoes (which may interfere with the absorption of essential nutrients), and it has 2 other sketchy ingredients, including Guar Gum and Canola Oil. 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 Health Extension recipe may be implicated in the FDA's ongoing investigation into diet-related Dilated Cardiomyopathy (or DCM), a potentially fatal heart condition.
