Lightlife Smart Dogs® are a clear nutritional upgrade from traditional hot dogs—free from cholesterol and saturated fat, yet delivering a solid dose of plant-based protein and iron. They’re low in total fat and sugar, but their sodium content and lack of fiber make them better suited for occasional use. While they won’t fool your taste buds into thinking they’re meat (but honestly, do any of us even know what’s in a real hot dog?), they satisfy the craving for a classic hot dog—minus the usual health baggage.
