Kangaroo meat was usedto make these tasty treats. That meat has been combined with cordyceps mushroom, which is used in traditional Chinese herbal medicine. The kangaroo meat is an excellent source of protein, and it is very low in fat. It contains few to no allergens and is ideal for pets who have digestion or allergy issues. The cordyceps offer lots of health benefits for your dog, and they are often used as a tonic for kidneys. These same mushrooms benefit your immune system, help increase stamina, fight poor blood pressure, improve cholesterol levels and oxygenate the blood.
