Dichromatic vision is a type of color vision in which there are only two types of color receptors in the eye.
Dogs can see shades of blue and yellow, as well as some shades of gray. They cannot see red, green, or purple.
Dogs see color by detecting the wavelengths of light that hit their eyes.
Dichromatic vision does not have a significant impact on a dog's ability to function in everyday life.
Some dogs may be color blind, but this is not the same as dichromatic vision.
There are a few ways to test your dog's color vision. One way is to use a color vision test card.
When choosing toys for dogs with dichromatic vision, it is important to choose toys that are brightly colored in blue or yellow.
