Peak Nutrition, Powered by Purpose
The spirit of Challenger is reaching beyond conventionally grown ingredients and choosing sustainability. With ethically-sourced ingredients like beef, duck, haddock, and organic grains like millet, oats, and barley, we can enrich the way we feed our pets.

Nutrition Meets Sustainability Challenger recipes use ethically-sourced proteins like beef, lamb, pork, haddock, salmon, duck, turkey, and guinea fowl. Organic ancient grains like millet, oats, and barley provide low-glycemic carbs while supporting sustainable agriculture.

Fueled by High Animal Protein
Nulo's Challenger line provides 32-35% protein content, with 83-90% derived from animal sources. Each recipe features animal proteins as the top ingredients, ensuring a high-protein diet that supports lean muscle mass and overall health.

Nourish Health with Premium Ingredients
Advanced prebiotics and BC30 probiotics aid digestive and immune health. Ancient grains, ethically sourced proteins, miscanthus grass and superfoods fuel optimal nutrition. Vitamins and omegas nourish immunity, skin, and coat.
