Purina ONE SmartBlend Sensitive Systems Adult Formula 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 24 synthetic additives (so it is not all-natural), it has 1 anti-nutrient, Dried Peas (which may interfere with the absorption of essential nutrients), and it has 3 other sketchy ingredients, including Chicken By-Product Meal (Source of Glucosamine) and Liver Flavor.

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