Love Darwin's! Have used it for a year.. I don't feed it exclusively, but find it is the best/ freshest prepared raw diet. I have the best success feeding Darwin's than any other raw diet, including home prepared. I have a standing order with them. I was at my Schutzhund training this evening, and out of 16 dogs, mine had the best body and coat condition. She positively glistens and her musculature is pronounced. Not to mention, she is a work-horse!
