Do Dogs Really Only See Black And White?

Veterinary research indicates that dogs do see colors, but that they can distinguish fewer colors than humans can. The mechanisms used for color recognition in both human and dog eyes are called cones. Dogs have cones, but fewer cones than humans. Thus, it is believed that while dogs can recognize and distinguish between certain colors, they do not see the full "rainbow" of the color spectrum that humans do. Don't feel bad, though, because some aspects of dogs' visions far surpasses our own. For example, dogs can see much better in dim light than we can. In addition, dogs are much better at detecting motion than are humans.
