When a wiggly little bead of light catches a dog's eye, nothing in the world matters more than capturing it. Unfortunately, "it" is just an ungraspable bundle of massless photons. The lack of closure in laser-beam chasing could be messing with your dog's head.
Dogs (and some cats) instinctively chase these bright-red dots simply because the dots move, said Nicholas Dodman, a professor of animal behavior at Tufts University's Cummings School of Veterinary Medicine. Movement automatically stimulates their innate prey drive (http://www.lifeslittlemysteries.com/1638-zoos-fake-hunts-satisfy-predators-killer-instincts.html)http://global.fncstatic.com/static/v/all/img/external-link.png, which explains why lower-on-the-food-chain animals such as rodents and rabbits often freeze in place as a survival strategy. Although dogs aren't so discerning when it comes to color (http://www.lifeslittlemysteries.com/2608-dog-color-vision.html)http://global.fncstatic.com/static/v/all/img/external-link.png, their eyes contain a high preponderance of light-sensitive cells called rods for top-notch motion detection.
