The science of color vision in dogs, explained in pictures. Have you ever wondered why dogs can spot the wagging tail of another dog from a great distance, but they can’t see a deer in tall grass standing nearby? Dogs do not see colors the same way that humans do. This meticulously researched book, firmly grounded in facts and the scientific method, describes the differences between human vision and canine vision. Learn about what kinds of tests have been used to find out what colors dogs can see. Try the color vision test with your dog, and draw your own conclusions. Any proceeds will be donated to Summit Assistance Dogs of Washington, a nonprofit organization that provides service and therapy dogs to people living with disabilities.
