How is dog view? Do dogs see different from humans?
Contrary to popular belief, dogs do not see the world in black and white. They do, however, see the world quite differently to humans.
Dog view is special because their retinas have fewer cones but more rods compared to humans. Color vision depends on the cone. The fact that they have a lower presence of cones means they do see colour, but in a differen way. The number of cones varies with the size of the dog breed, although that does not mean that smaller dogs view less than big dogs.
Dog view is dichromatic, so they primarily see blues and yellows, while humans see trichromatically, with visible variations of red, blue and yellow.
The higher presence of rods in dogs retinas, instead, means they detect movement and light better. Dogs, indeed, are much better than humans in low light situations and in identifying and catching moving objects.
Along the lifetime of a dog, its view can get les sharp, but still, senior dogs normally have good vision, since it is a crucial sense for these animals. If you are worry about your dog’s vision, we reccomend you to visit a veterinary to arrange a check up for you mascot.
