From the manufacturer:
A Physiologically Tuned™, nutritionally correct diet for your canine companion means meat first, limited ingredient recipes. Meat first provides canines the animal protein they need to thrive, while our limited ingredient philosophy eliminates troublesome staples such as Chicken, Corn, Wheat, Soy and Potatoes. The result is optimal hypo-allergenic, low glycemic nutrition. We build on this natural foundation by adding vital supplements such as antioxidants, essential fatty acids and a complete spectrum of vitamins and minerals for holistic pet food that goes beyond nature to become your pet’s signature food for life.
Our recipes mirror the true diet your pet’s ancestors thrived on. In the wild, while prey may vary from day to day, meals are limited in content. We follow this natural blueprint, and limit the number of ingredients in our recipes. This helps ensure proper digestion for your pet, while minimizing possible allergens and food sensitivities.
