Wolves established a diet hundreds of years ago by catching everything they consumed. Diets derived completely from the wild kept them lean, sharp and alert. Blue Wilderness Rocky Mountain Recipe with Red Meat for Large Breeds was created to feed that same spirit of adventure in today’s dogs, with real red meat, real vegetables and real fruit. Added glucosamine and chondroitin support joint health, which is important for large breeds. Multiple sources of protein from beef, venison and lamb help your pal absorb the maximum amount of nutrition.
