Dogs don’t see the world in the same way we do. This goes back to their ancestry as predators.
They have a wider peripheral vision than we humans do, so they can keep an eye on their prey and any predators endangering them or their pups. Their world is also seen in a multitude of red shades, sort of like the color TV on the blink. This is because they have far fewer cone cells than we have. For the wild canines, the importance of peripheral vision was much more important than the color of the prey. Undoubtedly they had other ways to differentiate one species from another, like their fantastic sense of smell.
I think this is fascinating- if we could change vision for a day with our dogs we might gain some insight into the lives and worlds of our dogs.
