As with other books published by the Hubble and Hattie Imprint, this book is accompanied by wonderful photographs, in this case by Tom Walters (for other examples please see "Among the Wolves: Memoirs of a Wolf Handler" and "The Truth About Wolves and Dogs: Dispelling the Myths of Dog Training").
Dogs are thinking, feeling, and highly sentient beings, and not "unconditional lovers."
The above books and countless others clearly show that dogs are deeply feeling and highly sentient beings, unique individuals with a wide range of personalities who are very much part of our lives, and that it is the shared emotions - what I like to call "social glue" - between these amazing nonhuman animals (animals) and humans that are at the root of our close and enduring friendships. Dogs actively make choices about the humans with whom they bond (and many other things), these choices can change over time, they are not unconditional lovers who think and feel all humans can or will be their best friends forever, and they need to feel free to make the choices that best suit them. Thinking of dogs as machines who don't consciously make and refine their choices - what they want and what they need - is severely outdated and incredibly unscientific, and those who once favored this reductionist view are in an extremely small and ever dwindling minority given the plethora of data on the cognitive, emotional, and moral lives of dogs and other animals (please see for example "What Do Dogs Know, Think, and Feel? A New Book Tells It All," "Dogs Are People, Too: They Love Us and Miss Us fMRI's Say," "The Social Dog: Behavior and Cognition," "Dog Behavior, Evolution, and Cognition," "Animal Sentience: Where Are We and Where Are We Heading?," "Searching for Animal Sentience: A Systematic Review of the Scientific Literature," "After 2,500 Studies, It's Time to Declare Animal Sentience Proven," and the numerous references therein). Perhaps even René Descartes would consider changing his views on animals given the enormous amount of empirical evidence on sentience.
