Concentrated organic Chaga mushroom powder combined with organic Canadian blueberries is powerhouse of an antioxidant. My superfood combination has the ability to boost your dog's immune system, protect your dog from oxidative stress, and is known to help relieve IBS. One of the amazing health benefits of chaga mushrooms is that they are also known to slow down the immune system that is on overdrive - like dogs with allergies and autoimmune disease like arthritis. And, by combining organic blueberries with chaga mushrooms, it can help encourage healthy tear ducts in your dog. 
Note: Your dog only needs a tiny amount and my jar size reflects that.
