Dogs: how do they see the world?

Dogs are man's best friend. It is often said that dogs have a different vision than humans. While some people claim that dogs have black and white vision, scientists claim that these animals can distinguish certain colors. Find out more about the issue in this article.

The world view of dogs

It's time to clear your head of the idea that dogs see the world in black and white. It is quite true that the visual capacity of our dear four-legged friends is much more limited than ours.

Thus, dogs have a monochromatic vision which is explained by the anatomy of the eye. The eye is made up of visual receptors that allow them to capture the different colors. This organ is also made up of cones without which the receptors will not be able to fulfill their role. The difference in eye anatomy between a human and a dog is the number of cones.
