How many colours can my dog see?

Dogs have dichromatic vision, which means they can see two primary colors: blue and yellow. This is different from humans who have trichromatic vision, which allows us to see red, green, and blue.

Dogs' color perception is limited because they have fewer color receptor cones in their eyes compared to humans. While they can't see the full spectrum of colors that humans can, dogs can still distinguish between various shades of blue, yellow, and gray. However, they have difficulty distinguishing between red and green hues.
