Purina One SmartBlend Chicken & Rice Formula was inspired by the science in nature, discovering the power of smart ingredients that work together for your dog"s whole body health. Like real chicken as the first ingredient. Why? Because it"s tastefully rich in protein. And just like puzzle pieces that fit perfectly together, chicken blends with grains and other ingredients to create a complete protein profile. See, it"s choosing ingredients that work better together than they ever could on their own that inspired us to call this bag of food SMARTBLEND.
