Nulo FreeStyle offers a wide range of dry, wet, freeze-dried raw, treat, and topper recipes to fuel your dog’s adventures. On average, 80-87% of the protein in our FreeStyle diets for dogs comes from animal sources, which provides your dog with the ideal amino acid profile! FreeStyle’s formulas are grain-free, using ingredients like sweet potatoes and chickpeas as low-glycemic, whole-food carbohydrate sources.
