Can Your Dog See in Color? Despite common misconception, your dog can see in color. He cant see the same range of color you see, but he can use color to distinguish between different objects. Scientists believed for many years that dogs could only see in black and white, but recent research has shown differently. In fact, dogs see colors the way a color-blind human sees them. Read on to learn how your dog sees the world in color... A sky of blue and grass of... gray? Because dogs have fewer light-catching cells, called cones, they can only see colors in the blue and yellow wavelengths. So they can see blue and yellow, but not red and green. Overall, their world is colored in yellow, blue and gray. Can they see light or dark colors? Although their color range is limited, dogs can see different shades of color. If seeing a rainbow for example, theyd see it in shades ranging from dark and light blue to gray, light yellow, dark yellow and dark gray. Tests show they detect items based on color and shade, so the ball you throw him might appear light yellow against the gray-looking grass.

They can see fast-moving objects, but cant clearly focus on objects up close, which might look blurry or out of focus.
