What Colors Can Dogs See?

Learning about what colors can dogs see helps you train your dog!


A dog’s eyesight is significantly different from ours, starting with the fact that they are red-green colorblind. What colors do dogs see best? While dogs can see the colors blue and yellow very well, reds and greens fade into yellows and browns. Dogs’ view of the world lacks much of the visual richness that ours has.

Additionally, dogs’ eyesight is also fuzzier; much of the detail we humans see is lost on our canine companions. While we humans strive for 20/20 vision, a dog’s eyes are more like 20/50 vision, which means dogs need to be approximately 20 feet away from something to see it as clearly as we humans see it at a distance of 50 feet.

What does this mean for our interactions with our dogs? It could help explain why their noses are so terrific: because their eyes aren’t! This is one reason why it’s important to let your dog explore the world with her nose sometimes, rather than constantly thwarting her attempts to sniff.

It’s also important if you’re doing any kind of training with dogs that involves asking them to make choices based on color. (See: “Are Canines Cognitive?“)

If you’re teaching color discrimination, you can ask your dog to choose between a blue ball or a yellow one, but don’t expect her to be able to distinguish red or green ones. This could be especially important for service dogs, who are often asked to perform object-selection tasks.

Want to be able to see how your dog sees the world? There’s a fun app for your phone called “Dog Vision”.

After you load it you just point your phone at something and it will show you how that thing, or that scene, looks to your dog. Give it a try… it’s a real eye opener!
