ORIJEN dog food is my favorite all natural dog food! ORIJEN dog food is high-protein, low-carbohydrate and grain-free with a Biologically Appropriate ratio of 70 percent meat, 30 percent fruit and vegetables and zero grain. ORIJEN’s high-protein formulas eliminate the need for grains (which are inexpensive but inappropriate energy sources), and as high-protein diets are naturally more satiating, dogs naturally consume less ORIJEN than they would any other commercial pet food.
