Rough Greens is not dog food, but because dog food is dead food, it needs to be supplemented with live, powerful nutrition. Go ahead, take a bowl of your dog's kibble and put it on a shelf and see what happens after two to three years. You know what happens? Nothing. No mold, no bacteria, nothing happens. Because you know why? There's nothing alive in it.
