Alexandra Horowitz, a cognitive scientist, explains how dogs perceive their daily worlds, each other, and that other quirky animal, the human. Horowitz introduces the reader to dogs' perceptual and cognitive abilities and then draws a picture of what it might be like to be a dog. What's it like to be able to smell not just every bit of open food in the house but also sadness in humans or even the passage of time? How does a tiny dog manage to play successfully with a Great Dane? What is it like to hear the bodily vibrations of insects or the hum of a fluorescent light? Why must a person on a bicycle be chased? In short, what is it like for a dog to experience life from two feet off the ground, amid the smells of the sidewalk, gazing at our ankles or knees? Inside of a Dog: What Dogs See, Smell, and Know explains these things and much more, including research on dogs' ability to detect diseases in their owners, the secrets of their tails, and their skill at reading our attention. Although not a formal training guide, this book has practical application for dog lovers interested in understanding why their dogs do what they do. With a light touch and the weight of science behind her, Horowitz examines the animal we think we know best but may actually understand the least.
