For over 30 years, Blackwood has perfected the Slow Cooked Difference to preserve the natural flavor, quality and the nutritional content of each ingredient. Our new Blackwood Recipes were formulated by pet nutritionists to include essential nutrients, vitamins and Zinpro ProPath minerals to promote healthy digestion, boost skin and coat health and help strengthen your pet's immune system. Blackwood Lean Senior Diet is formulated with amino acid (L-carnitine) to help your dog maintain a healthy weight and muscle mass. Made with chicken meal and uses ancient grains as a source of fiber in lieu of grains like corn, wheat, and soy. Our recipes include more than the minimum AAFCO Required nutrients because your furry companion deserves more than the minimum.
