One of my favorite Canidae products. Why? #1, made in the USA. All of the companies products are made with out corn, wheat, soy, grain fractures or fillers and they're all naturally preserved. Released in 2010, the nutritional focus of Canidae Single Grain Protein Plus, is to offer 29% total protein while restricting its food grain sources to rice. Exclusively using a wholesome combination of both brown and white rice. Additionally, it offers 5 high quality protein sources in total. Beginning with fresh chicken and followed by chicken, turkey lamb and fish meals.
