But after all, what colors do dogs see?
The colors of canine vision
Dogs have a visual perception that is different from humans. While humans have trichromatic vision, with the ability to distinguish a wide variety of colors, dogs have dichromatic vision, which means they see the world in just two main colors: shades of blue and shades of yellow.
It is believed that the dogs have cone receptors sensitive to blue and yellow, but not to the wavelengths corresponding to green and red. Therefore, they cannot distinguish between colors like humans do.
Dogs compensate for their limited vision with other heightened senses. For example, they have an ability to detect subtle movement.
Imagine you trying to throw a tennis ball for a human from one room to another - the probability of missing is high! But an attentive dog could easily follow the trajectory of the ball.
Who needs all the colors when you have a keen sense of smell and peripheral vision to envy? You dogs have very developed peripheral vision.
While we can only clearly see what is directly in our line of sight, dogs can detect things moving around them without even looking directly at them.
However, dogs' visual acuity is also lower than humans', which means they can't see fine details or objects in the distance as clearly as we can.
While a person with good eyesight may to see objects up to 22 meters away, dogs have a visual limitation and can only clearly distinguish details at a distance of up to 6 meters.
