Agree, How do dogs really see the world?

According to some studies this is the case Is it just an urban legend?

The first scientific studies into the color perception of dogs date back to the 1940s.

Written by optometrist Gordon Walls “The vertebrate eye and its adaptive radiation” The book contains experiments on how dogs see colors. A 1913 experiment used only seven dogs, and as a result of this experiment it was claimed that dogs could distinguish shades of gray better than other colors.

However, the limited number of participants in these experiments and the technological limitations of the period meant that the results were misleading. The work of walls Although it took the first steps towards the canine visual system, it has largely lost its validity compared to current scientific knowledge.

Today it is known that dogs have a color perception that is “dichromatic”, that is, limited to two cone cells.

This means that they are not really color blind, but see certain colors. It is true that we have received wrong information on this topic in many films or stories. However, research by Jay Neitz and Gerald Jacobs from 1989 showed this It shows that dogs can see blue and yellow, but cannot distinguish between shades of red and green.

There are two types of cone cells in the retina of dogs. This makes them similar to other mammals such as cats, cattle and pigs. Although we have three types of cone cells, in dogs there are only two types. So they see the world in a narrower color spectrum.

They can easily distinguish blue and yellow colors.

However They cannot see red and its shades as clearly and vividly as we do.they usually see this color in shades of gray or brown. The fact that the colors they can perceive are limited does not, of course, change the fact that dogs see the world in color.
