About this product
Give your growing large breed puppy an elite nutritional foundation with Nulo Challenger Alpine Ranch Large Breed Puppy Recipe. This "Alps" inspired, ultra-high protein diet features a robust and savory blend of beef, lamb, and pork, providing a diverse and critical amino acid profile to support developing muscles and heavy frames. Prepared with up to 90% animal-based protein, it mimics a canine’s ancestral eating habits while perfectly scaling the nutrition for large breed growth.
The recipe combines fresh beef and lamb with organic oats and barley, offering a highly digestible, low-glycemic carbohydrate source for sustained energy without the sugar spikes. It is meticulously fortified with Nulo's signature GanedenBC30 probiotic to support optimal gut health and metabolic function, along with balanced calcium and phosphorus for controlled bone growth. This premium formula contains no corn, wheat, soy, or artificial preservatives.
Available in a bulk 24 lb bag perfectly sized for large breed puppies, Challenger Alpine Ranch serves as an exceptional choice for pet parents seeking a high-meat diet with the heart-healthy benefits of ancient grains. It establishes a lifetime of health from the very first bowl.
