I'm bringing home a new Westie puppy in a few days and am in obsessive mode about learning and deciding which is the most optimal diet for my new baby. Just read Dr. Ian Billinghurst's book, "Give Your Dog A Bone". I thought it was excellent and have been all revved up to follow his plan. But then I find this article about a Prey-model diet. This author (Lily Allyn) refutes the notion that dogs are omnivores, says they're carnivores and therefore should eat whole-prey food. She makes a compelling case and now I'm vascillating. My new puppy has an outstanding pedigree and if she proves to have the qualities of a champion by the time she's 6 months old I plan to show her. I'm worried that a Prey-model diet might keep her too lean to develop into a show dog. Anyone out there have experience with these diets, or is an avid reader and obsessive researcher like I am and can contribute to my education?
