Based on this biological fact, and to produce a nutritional analysis that mirrors the diet Mother Nature would provide for your dog, ACANA Pork & Squash is rich in nourishing proteins and fats, while limiting unwanted carbohydrates. ACANA mirrors the natural diet, applying our Meat Math and incorporating WholePrey meat, organs and cartilage in ratios that deliver nutrients naturally. By providing a concentrated and natural source of virtually every nutrient your dog needs to thrive, you eliminate the need for long lists of synthetic additives. That's why zinc is our only added supplement. ACANA Pork & Squash features an unmatched variety of local ingredients that are raised by people we know and trust, deemed "fit for human consumption", and then delivered to our Kentucky DogStar kitchens fresh each day!.
