Inspired by the fertile Kentucky grasslands, this biologically appropriate recipe includes an unmatched variety of fresh regional ingredients including grass-fed Kentucky lamb, free-run Muscovy duck, nest-laid eggs, rainbow trout and free-run quail! All ingredients are raised and fished on local Kentucky farms by farmers and fishermen ACANA knows and trusts. All meats are deemed fit for human consumption before arriving fresh and whole to ACANA's Kentucky DogStar Kitchens. Staying true to your dog's evolutionary diet, ACANA formulas feature WholePrey ratios in order to mimic the diet mother nature intended so your dog can maintain optimum weight and peak health. By using the whole animal or fish, including organs and cartilage, your dog absorbs all the necessary nutrients naturally and completely. Muscle meat provides protein; liver, kidney and tripe supply vitamins and minerals; while bones and cartilage deliver calcium and phosphorus. Glucosamine and chondroitin are derived naturally from high quality meat ingredients, not synthetics. Fresh whole Rainbow trout are brought in daily from Idaho's Snake River aquifers and are naturally rich in essential fatty acids like omega-3, DHA and EPA to promote healthy skin and shiny coats. A fresh assortment of fruits and vegetables are brought in from neighboring farms to provide a tasty and natural source of vitamins, minerals and amino acids necessary to keep your dog in peak physical health.
