The dogs Not only are the best friends of the human being, they are also animals with Sensory skills very different from ours. From their powerful sense of smell to their ability to detect human emotions, these four -legged pets have evolved over thousands of years to become smart, loyal and very perceptive companions.
30,000 years ago, they were the first animal domesticated by the human race. This is largely due to your “Supersentido”: The smell. Dogs have an anatomical structure in their nasal cavity capable of perceive odors that no human gets to capture. For this reason, for example, canines are part of the rescue groups and security agencies of each country.
However, they do not have so many skills in regard to 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 whiteas many believed. This research revealed what is the true range of colors that these animals can perceive and contributed new findings about their visual capacity. I discover them!

No more black and white? These are the colors that our dog can see
According to the ophthalmological center of Barcelona, human beings have about 6 million cones and 110 million canes in our body, fundamental parts of the eyes to distinguish colors. This immense amount allows us to better perceive tones Red, green and bluemaking our vision Tricromatic.
While, on the other hand, dogs prove to have a significantly lower amount of cones, although the numbers vary according to the races. This reduction causes a Dichromatic vision In animals, and it is for that reason, that they have a limited perception compared to people.

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 predominantly colored scale Blue and yellowin addition to several grays. This affects its interaction with the environment and the interpretation of visual stimuli, so it is understandable that they have ultra developed smell and hearing.
Along these lines, the attached study in the magazine Psychonomic Bulletin & Review He also discovered other issues related to vision, such as dogs are usually more sensitive and perceive ultraviolet light. In addition, they are able to make the most of the minimum available light, which allows them to better see than humans under conditions of Low lighting.
And finally, its visual field is broader than ours, getting to extend until 240 ° In some races. This gives them a peripheral vision much more developed than that of people, which only reaches 180 °.
