For a long time, many people believed that dogs could not distinguish colors. Recently, researchers have discovered that dogs can distinguish different shades of gray, as well as certain colors, particularly blue and purple.
Dogs’ far-sightedness is much higher than that of humans, and their field of vision is actually wider than that of humans. A dog's binocular field of view can reach 250°-300°, while a human's binocular field of view is only 180°.
In addition, dogs can see far better in the dark than humans. Because dog eyes contain many cones and rods, especially rods that are sensitive to low light. Many times when dogs bark for no reason in the dark, it is because they see places that your vision cannot reach.
