Do Dogs Only See Black and White?

Research indicates that dogs do see colors, but that they can only distinguish fewer colors. The mechanisms used for color recognition in both people and dog eyes are called cones. Dogs have cones, but they have fewer cones than people. 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 people 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 people.
