About this product
Give your growing puppy a robust nutritional foundation with Nulo Challenger Alpine Ranch Puppy Recipe. This ultra-high protein dry dog food features an "Alps" inspired blend of premium beef, lamb, and pork, providing a rich, diverse amino acid profile to support rapid muscle development and high puppy energy. Prepared with up to 90% animal-based protein, it is expertly designed to mimic a canine’s ancestral carnivorous diet.
The recipe combines fresh beef and lamb with organic oats and barley, offering a wholesome, low-glycemic carbohydrate source for sustained play and growth. It is fortified with Nulo's patented GanedenBC30 probiotic to ensure healthy digestion and a strong immune system from an early age. This nutrient-dense formula contains absolutely no corn, wheat, soy, or artificial preservatives.
Presented in a 24 lb bulk bag, this formula is an excellent choice for dedicated owners who want a high-meat diet combined with the heart-healthy benefits of ancient grains. It provides complete and balanced nutrition for your puppy's most critical growth stage.
