I have had two printings of this book. Not only is it good for learning how to make a homemade diet (or supplement one that is store bought), but it is a great reference for ailments your vet diagnosis. Homeopathy, flower essences and a few herbals are covered in this book. Those listed are usually things that can be done at home without bad consequence as well as along with conventional medication prescribed by your vet. This is a valuable book that should be used in CONJUNCTION with (not instead of) veterinary care. Obviously, I highly recommend it.
