COLOR VISION IN DOGS
Dogs are not color blind, but they
have poor color vision. In comparison
to humans, dogs not only see
fewer colors but also a more faded
version of the colors we see.
A dog’s eye contains more rod
shaped cells than cone cells. Fewer
cone cells are the reason why dogs
perceive colors lighter than they exist.
In addition to this, a dog’s eyes
contain only two of the three types
of cone shaped photoreceptors.
Thus, they see only certain colors of
the color spectrum and are said to
have dichromatic vision.
