Dry dog food with real lamb as the first ingredient, blended with other high-quality protein sources helps support strong muscles, including a healthy heart. In our lamb and rice formula dog food, real lamb is our first ingredient. Why? Because it's tastefully rich in protein. And just like puzzle pieces that fit perfectly together, lamb blends with grains and other ingredients to create a complete protein profile. 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.
