Do Dogs Have Dichromatic Vision?

Human eyes have three types of cones that can identify combinations of red, blue, and green. Dogs possess only two types of cones and can only discern blue and yellow - this limited color perception is called dichromatic vision.

Do dogs have special vision?

Dogs have rod-dominated retinas that allow them to see well in the dark. Along with superior night vision, dogs have better motion visibility than humans have. However, because their retinas' contain only about one-tenth the concentration of cones (that humans have), dogs do not see colors as humans do.

What is dog vision called?

This means that people can normally identify three color combinations (red, blue, and green), while dogs are limited to two (yellow and blue). Dog color vision is therefore described as dichromatic, or “two-colored.”
