I ordered this book to add to my Natural Health library for pets.As a regular reader of "Preface" and "About Author" pages, I started reading them in Dr. Shelton's book. An interesting evolution from conventional veterinarian to the Oily Vet. But what is most valuable to man and beast is what happened to her baby, herself, her family and then the pets she treats. It is the eye-opener which makes this book the gem it is.Goodness, if only people will learn and understand the evil poison corn syrup and all its various forms is and what major damage they do to the human and animal body. Between these manipulated sugars, also artificial sweeteners, our systems do not know how to process them and thus the many allergies, skin problems, cancers and all the other diseases which have been plaguing people and pets since about the 1970s when corn syrup was introduced and placed into almost everything, in ever increasing numbers. Why do we have to have corn syrup in dog food? Just read the labels. It is insane.If we want to stay and get healthy, we must take responsibility for our own and our dependents' well being. Books like Dr. Shelton's book are great additions to such education.I very much like the inclusion of not only therapeutic essential oils, but also the nutritional supplements that can and should be added to pets' regular nutritional regiments.The section on arthritis in dogs (pg. 65-70)is excellent and probably will add many happy years to many a pet, even if they currently suffer. Good information for horses, birds, and other pets. There is a great section on the issue of cat litter - more information worth the book.I do not know Dr. Shelton, but if her office were within a 100 mile radius, I'd be heading her way for my pets' maintenance.The one thing I find missing and urgently suggest to be included in future editions is an INDEX.When in a hurry, an index makes life so much easier.
