Ozzy and Sharon Osbourne have put their pet pooches on the latest Hollywood diet consisting only of specially prepared raw food. The pampered pets are now following the BARF diet - Biologically Appropriate Raw Food. The all-natural, hormone-free food is free from the grain-based kibble that's usually found in store-bought pet food and consists of finely ground bones, which are said to be full of minerals. The bone-mixture is combined with raw chicken, beef, lamb and even unbleached tripe (the lining of a cow's stomach).
