When Visa was on kibble I tried TimberWolf Organics -- I finally had to switch her off of it. She lost so much weight. All of her stools for a month were black and tarry (which means there is blood in the stool) piles of diahhrea. I had the bag left over so I tried the food on my foster puppy -- same effect -- Bloody diahhrea. Everyone I talked to who had tried it had the same experience. I don't know what it is about the food, it has great ingredients compared to most kibbles.
