I read this book cover to cover, except the cat section. It is a good way to learn about the dog food industry, co-packers and that dog food is an entirely unregulated industry. The pet food companies that she recommended were interesting, but most foods listed as a "5" or "6" on Dog Food Analysis were not researched. It is definitely not a substitute for the Dog Food Analysis website. The recipes for cooking for your pet were nice, but the author did not mention what portion sizes were recommended. It was a a quick read and worth the time, but I have found more nutritional guidance on this website than in the book.
