The spirit of Challenger is reaching beyond conventionally grown ingredients and choosing sustainability – to give the world around us a chance to heal and renew. Peak nutrition doesn’t have to be at the expense of our environment. 

Canine legends aren’t born. They’re made. While Pea Protein and Potato Protein are ways many brands boost the protein in their foods, we believe animal-based proteins contain the optimal amino acid profile to help them run at the front of the pack.

Our dogs have many great moments ahead of them, so let’s provide them with nutrition that nourishes their mind, body, and soul for years to come.

Slowly simmered for up to 48 hours to extract nourishing protein and infused with herbs and spices. 100% Human-Grade ingredients made in a Human Food facility. Pour over your dog or cat’s favorite kibble or freeze-dried food for a delicious flavor boost. Available in 3 flavors: Grass-Fed Beef, Organic Chicken, and Wild-Caught Salmon.

Nulo is proudly made in the U.S.A. using the highest quality ingredients. Our foods are produced in FDA-approved facilities and our dry food kitchen receives an annual inspection by the American Institute of Baking (AIB) and has consistently received "Superior" ratings.

Treat your senior dog to a superior nutrition plan that keeps them fit and healthy for years to come.
