    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, 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, their eyes contain a high preponderance of light-sensitive cells called rods for top-notch motion detection.

    A laser beam's incessant movement keys into this predatory system. "They can't help themselves; they are obliged to chase it," Dodman told Life's Little Mysteries.

    The people we got Nisa from thought this was a cool thing to teach a Border Collie.
    Not a good idea. She will now chase or bark at light reflections on the ceiling, lightning bugs, flashlights and embers flying out of fires.
    I just barely was able to stop her from jumping into a smouldering leaf pile one time when some acorns were popping and throwing sparks.

    Thus, an example of a dog that was driven nuts.
