Benny Bullys NutriMix is made from 100-Percent PURE AND NATURAL INGREDIENTS. We choose government inspected and no offshore sources for health and safety. We start with pure beef liver and infuse our recipe of "back to basic" real food ingredients: Sweet Potato, Banana, Apple, and Pumpkin. Rich in protein (but less than pure liver), rich in vitamins and nutrients, they make a healthy dog treat or training reward. Also can be used by adding to pet food, to enhance flavour.
