Due to a doggy's ability to see with red-green color blindness, their vision is actually quite good! Watch and be amazed as your pooch warns you of what she may think is a potential threat in the distance. Without her skills for the motion you may have not even known something was there!

While their color vision is somewhat limited and different than ours, they do see color, and a look at the world through a dog’s eyes can provide insight into how they perceive the world.
Humans see the world in color because we (usually) have three types of color receptor cells, or cones, in our eyes.

Some humans, however, are colorblind, which is a generic term for various changes in color perception.

For dogs, their color vision is most similar to a human with red-green color blindness, although there are other differences. Dogs are less sensitive to variations in gray shades than humans are, as well as only about half as sensitive to changes in brightness.

However, dogs do outperform humans in some visual abilities. Dogs are much more sensitive to motion at a distance — anywhere from 10 to 20 times more sensitive than humans. Their vision is also well-suited to hunting during dawn and dusk.

Along the way, mammals began to lose all the extra receptors until only two remained. Since this didn’t put dogs or other predators at a particular disadvantage for hunting, it didn’t make much of a difference. It was only later on that some primates, including humans, re-evolved and added the additional receptor that gives us full color vision.

So the next time someone tells you that their pooch only sees in black and white, you can explain what is true! It turns out your doggy can see a lot more than you may have originally thought. And your pooch can also warn you of danger. So while you're enjoying the scenery in the distance your doggy may also be doing the same! Cesar's Way elaborates more on this fascinating topic.
