Como um cachorro enxerga?

People consider dogs to be their best friends. And in many ways, these animals are the closest to us of all creatures on the planet. Therefore, it is not surprising that a person is interested in how a dog perceives the world around him. For example, how a dog sees, and in particular, whether dogs see colors.

First of all, it must be said that dogs rely more on their ears and nose than on their eyes. Therefore, the vision of our best friends is inferior to ours. And “sharpened” by nature in a different way than ours.

For example, dogs cannot see stationary objects well. But the movement is very good, much better than us. Especially the movement is abrupt or unusual. This was necessary for the detection and capture of prey. 

There used to be a myth that dogs can’t see colors. This is not true. Dogs see many colors, but some are better than others. For example, dogs cannot distinguish between green and red. Also orange and red look the same to them. But they distinguish yellow, blue and light green colors well.

Dogs are better at navigating grayscale than humans.

Dogs are also better than humans at seeing in the dark, able to discern more details in low light. Therefore, they need less light than we do.
