Ok, I know I don't have the ability to prepare raw food, plus for me it would gross me out. However, I finally looked at Ziwipeak after reading about it over and over again here. I have a question, how long would an 11 lb bag last feeding a 5 pound adult dog? I generally feed her twice a day. When I feed dry she gets 1/8 cup. I'm trying to look at this on a cost basis. I would buy from amazon since I am a prime member and get free shipping. Thanks!
