Debunking the myth: Do dogs really see in black and white?

One of the most persistent myths about dogs is that they are colorblind and only see shades of gray. This misconception dates back to early scientific studies that were misinterpreted, leading many to believe that dogs were incapable of seeing color. However, recent research has led to a clearer understanding of the canine visual spectrum and shown that dogs can indeed see color, albeit differently than humans.

The truth about dogs’ color vision

Dogs' eyes have two types of color receptors called cones that are sensitive to wavelengths of light. Humans, on the other hand, have three types of cones that allow us to see the full spectrum of colors, including red, blue, and green. Dogs lack the receptor for red, which means their color vision is somewhat similar to color vision loss in humans - often referred to as red-green color blindness.

What colors can dogs see?

The color spectrum visible to dogs includes shades of blue and yellow. This means that certain colors that are bright to humans, such as red or orange, may appear more brownish or grayish to a dog. However, blue and purple appear blue to dogs, while green and yellow may resemble each other and tend to be more yellow.

Impact on dog owners

Understanding that dogs see the world differently can help dog owners make more informed decisions about everything from choosing toys to decorating their homes. For example, toys that are blue or yellow are more likely to catch a dog's eye in a green field than toys that are red or green.
