I admit our dog Bactisel in acute or mild diarrhea. Simply sprinkle over the food, a measuring spoon is included. The powder is very good and fast, it builds the intestinal flora again. Since we have the problem more often because our dog is a dog from the shelter fear, I am glad that there is such a means and not one must resort to tablets! And you can give calmly over a longer period, or only when needed. In addition, we provide one to two times more carrot pellets which also helps well over his food!
