By nature, all dogs have evolved as carnivores, biologically adapted for a diet rich and varied in fresh meats with smaller amounts of vegetables, fruits, and botanicals. They might look different, but your dog shares his eating anatomy with the gray wolf. Based on this biological fact, and to produce a nutritional analysis that mirrors the diet Mother Nature would provide for your dog, ACANA Puppy & Junior is rich in nourishing proteins and fats, while excluding rice, potato and tapioca and long lists of synthetic ingredients found in some dog foods. ACANA Puppy & Junior is formulated to meet the nutritional levels established by the AAFCO Dog Food Nutrient Profiles for All Life Stages. Our award-winning Biologically Appropriate philosophy is simple: mirror the quantity, freshness, and variety of meats that dogs have evolved to eat, while limiting the long lists of synthetic ingredients that don’t belong in your dog’s natural diet.
