In our Large Breed Adult Formula Dog Food, real chicken is our first ingredient, along with other key ingredients and nutrients including rice and glucosamine. Why? Because feeding a large breed dog is a balancing act. An ideal body condition helps minimize stress on bones and joints. And the right balance of vitamins, minerals and other nutrients helps them live large, healthy and strong. It's choosing ingredients that work better together than they ever could on their own that inspired us to call this dry dog food SMARTBLEND.
