The dogs They are part of most Argentine households and families. People choose to live and establish relationships with them for their loyalty, Unconditional love and ability to provide company.
In addition, they were the first animal domesticated by the human race 30,000 years ago and have an anatomical structure in their nasal cavity capable of perceive odors that no human gets to capture. This “Supersentido“Of the smell, the canines are part of the rescue groups and security agencies of each country, such as, being a complement of great value the armed forces.
But, on the other hand, they do not have so many skills in the vision sense. For years we tried to explain the supposed daltonism of our dogs, and such interest, led researchers to discover how this capacity works. Focusing, mainly, finding the answer to a key question: What color do dogs see?
A study published in the magazine Psychonomic Bulletin & Review He collapsed myth that our canines see in Black and white. This research revealed what is the true range of colors that these animals can perceive and contributed new findings about their visual capacity.
No more black and white, what colors can our dog see?
According to the ophthalmological center of Barcelona, human beings have about 6 million cones and 110 million canes, fundamental parts of the eyes to distinguish colors. This immense amount allows us to better perceive tones Red, green and bluemaking our vision trichromatic.
While, on the other hand, dogs prove to have a significantly less cones amount, which vary according to races and produce a Dichromatic vision In animals. That is why they have a limited perception compared to humans.
As for the vision of color, they are unable to distinguish between two tones such as red and green. Instead, dogs see the world on a scale of predominantly blue and yellow colors, in addition to several gray, which affects their interaction with the environment and the interpretation of visual stimuli.
On the other hand, the study also discovered that dogs are usually sensitive and perceive ultraviolet light; They can make the most of the minimum available light, which allows them to see better than humans under conditions of Low lighting; And its visual field is broader, extending to 240 ° In some races. The latter gives them a peripheral vision much more developed than that of people, which only reaches 180 °.
