Hill's Prescription Diet r/d Weight Reduction Original 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 22 synthetic additives (so it is not all-natural), it has 3 anti-nutrients including Soybean Mill Run, Soybean Meal, and Soybean Oil (which may interfere with the absorption of essential nutrients), and it has 3 other sketchy ingredients, including Powdered Cellulose and Chicken Liver Flavor. 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 Hill's Prescription Diet recipe may be implicated in the FDA's ongoing investigation into diet-related Dilated Cardiomyopathy (or DCM), a potentially fatal heart condition.
