In addition to the Venison Meal, Lamb Meal and Chicken Meal formulas in the California Natural line, a Kangaroo & Red Lentils formula and Salmon Meal & Peas formula were added for adult dogs. The two new formulas are available in 5 lb., 15 lb. and 30 lb. bags. The dog food can be purchased at independent pet specialty retailers beginning in November 2011.
