This is an only slightly revised/updated version of Schultze's original spiralbound book "The Ultimate Diet." There are several books on feeding natural/raw/whole foods to dogs, and Schultze's book is the most restrictive, as it does not allow any grains, dairy products, blackstrap molasses, or raw honey (which many experienced breeders using holistic methods consider a "must" in dog rearing). Unfortunately many people new to raw feeding read Schultze's book and become convinced that giving their dogs even small amounts of whole grains or a little yogurt with raw honey is tantamount to poisoning them! Those of us who have been feeding a fresh foods diet for decades know that nothing is farther from the truth, but Kymythy believes that *all* dogs do better without grains, dairy, honey, etc., and of course her book includes testimonials only from people who agree with her. While it's true that some dogs do indeed fare better on a no grains/no dairy diet, others do much better on a more varied diet that includes small amounts of whole grains, yogurt or kefir, blackstrap molasses, and other foods Schultze feels should be avoided.
My biggest problem with this book, however, is that Schultze repeatedly passes of some rather controversial opinions as scientific fact. Not surprisingly, no footnotes are provided to back up any of her claims. She also uses the cancer research from Colorado State's veterinary school to imply that feeding grains and dairy products causes cancer. While it's correct that a diet high in certain fats and low in simple carbs is recommended for dogs with cancer (as well as those in remission), there is absolutely no evidence that a diet without grains and dairy products helps to *prevent* cancer. In fact, even the cancer diet recommended by Colorado State includes small amounts of whole grains. Cancer causes metabolic changes in the body which makes what is optimal for dogs with cancer not necessarily optimal for healthy dogs.
Of course I'm not recommending a grain-based diet (I agree that raw muscle and organ meats and meaty bones should make up the bulk of the canine diet), but small amounts of whole grain and cultured dairy products (e.g., yogurt, kefir) can add variety and valuable nutrients to the diet. Dogs, like humans, are individuals and it's important to remember that there is no one diet that is perfect for every dog.
Depending on the exact composition of Schultze's diet, deficiencies in certain nutrients are quite possible, and I would definitely not recommend a diet so low in carbohydrates for in-whelp bitches. On the other hand, if you have a dog with cancer or allergies to grains/dairy, this diet may be just what you've been looking for. It's easy to follow, but I do suggest reading a little more on canine nutrition.
