Natural Balance Synergy 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 26 synthetic additives (so it is not all-natural), it has no antinutrients like peas, lentils, or potatoes (which is great, because these ingredients may interfere the absorption of vital nutrients), and it has 3 other sketchy ingredients, including Brewers Dried Yeast and Natural Flavor.

Warning In June 2019, the FDA implicated Natural Balance's dog food in at least 10 cases of Dilated Cardiomyopathy (or DCM), a potentially fatal heart condition.
