Do Dogs See In Color? New Study Shows Canines Do Depend On Color Perception
How do dogs see the world? A lot more colorfully than you might have imagined, new research suggests.
Scientists have long known that dogs' eyes are physically equipped to perceive colors, and consequently that canines are not colorblind. (http://www.medicaldaily.com/articles/17542/20130718/dogs-see-color-black-white-what-means.htm) But dogs are believed to see only shades of yellow, blue, and gray. That's because their eyes have only two types of color-sensitive "cone" cells (http://www.livescience.com/34029-dog-color-vision.html)as compared to three in the human eye.
Given their limited color "rainbow," do dogs really make use of their color vision to make decisions -- or do they depend solely on levels of brightness?
