If you keep wondering why your dog does not love picturesque landscapes and doesn’t admire the colors of Van Gogh paintings, there’s a reason for all these phenomena. The answer is they just do not see the world the same way humans do. And here is what the differences are.
Many people believe dogs see in black-and-white, but that’s not correct. In fact, a vision of a dog is similar to a vision of a person with red-green color blindness. That said, they don’t see some colors, so the picture gets grayish in some areas. Besides, the way they detect different shades of grey and brightness is also not like that of humans’.
Colors: A human eye has two kinds of color receptors, namely cones and rods. Cones can be of several types, each of which processes a certain light wavelength, while the latter are used to differentiate shades of gray and ensure night vision, as well as brightness and peripheral vision processing.
Humans with normal vision have three types of cones, so they can see all colors by mixing the ones detected by the cones (like in painting, blue and yellow make green, etc.). Unlike humans, dogs have only two types of cones (the same way as people with red-green color blindness do), so their vision provides them with way less vibrant pictures.

Besides, they see everything rather blurred, and shades of gray are not that contrasting. Near-sightedness is another peculiarity of dogs’ vision.
Yet these drawbacks are compensated by the marvelous smelling capabilities of dogs, which means they can use their nose to comprehend things that are not recognized by the eye.
