One of the most common dog myths is that dogs are colorblind. They can see some color, but the spectrum is limited compared to human color vision. This is because our canine buddies are dichromatic, meaning their eyes only have two kinds of the cone cells that control color perception. Humans and most other primates have three kinds of cones, making us trichromatic. For an approximation of how your dog sees the world (similar to a person with red-green color blindness), you can check out the Dog Vision online tool. That orange squeaky toy just might look blue to your pooch!
