While our crunchy Marrow has been naturally air-dried, it originally has the consistency of a fatty gelatin substance. The marrow is found in the center or core of lamb bones and horns. Dogs are drawn to the marrow, as its a very nutrient-dense and highly rich dietary energy source. It contains a high content of minerals (calcium), essential fatty acids, vitamins, and lipids (alkylglycerols). Whats even more exciting is that ourHorn Marrow Chips support the canine immune system by carrying oxygen to cells in the body. When your furry friend eatsLambMarrow, its helping to improve brain function, support their immune system, speed up the healing process from an injury, and promote the maintenance of healthy bones. In short,Lamb Marrow is a great source of natural and nutritious healing energy for your pet!
