Purina ONE SmartBlend Small Breed Lamb & Rice Formula 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 25 synthetic additives (so it is not all-natural), it has 3 anti-nutrients including Soybean Meal, Soybean Oil, and Dried Peas (which may interfere with the absorption of essential nutrients), and it has 5 other sketchy ingredients, including Glycerin and Caramel Color.

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.
