Book Review - 'Inside of a Dog - What Dogs See, Smell, and Know,' by Alexandra Horowitz

A human being experiences a rose as a lovely, familiar shape, a bright, beautiful color and a sublime scent. That is the very definition of a rose. But to a dog? Beauty has nothing to do with it; the color is irrelevant, barely visible, the flowery scent ignored. Only when it is adorned with some other important perfume — a recent spray of urine, perhaps — does the rose come alive for a dog.
