vs

Purina ONE SmartBlend True Instinct Classic Ground with Real Beef & Wild-Caught Salmon 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 1 anti-nutrient, Locust Bean Gum C421417 (which may interfere with the absorption of essential nutrients), and it has 1 other sketchy ingredient, 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 Purina ONE recipe may be implicated in the FDA's ongoing investigation into diet-related Dilated Cardiomyopathy (or DCM), a potentially fatal heart condition.
