Kefir! Think of it as yogurt on steroids. It's probiotic, made from milk and is slightly effervescent. It has contains ten active "friendly" microorganisms, compared to two or three in yogurt. For people, it helps prevent common side effects from taking antibiotics, helps with lactose intolerance and weight loss. Plus, it's an excellent source of calcium, protein and fiber. What does it do for my dogs? Who knows. All I know is that they like it.
