If you give your dog a great raw diet livers an important part of it. Its really a superfood for dogs!

Even though the liver cleanses toxins from the body, it doesnt store those toxins.

In fact muscle meats are typically higher in unwanted toxins than liver.

Some people compare liver to nature’s multivitamin. Thats because its rich in so many important nutrients:
-Vitamin A a powerful antioxidant. It supports digestion and reproductive organs.
-Vitamin D a vitally important nutrient for immune function. It helps protect against cancers, autoimmune and infectious diseases. It supports muscle and bone strength too.
-Folic acid, B vitamins support mental and nerve health. They help avoid fatigue and prevent anemia.
-Iron forms hemoglobin, brain function, regulates body temperature. Iron transports oxygen to the blood cells. This increases your dogs endurance and strength. Lack of iron depletes antibodies and T-cells in the immune system.
-Other minerals (like copper and zinc) support bone and joint health, skin, coat, immunity.

And of course, livers a great source of protein thats also lower in fat than muscle meat.
