The perception of the world for us is based primarily on vision, but with dogs, everything is completely different. Scientists from Cornwall University conducted several experiments and learned how our pets really see everything.
It turns out that most dogs rely on their sense of smell. There are many smells flying around, but most of them a person is not able to smell. In addition, many smells will not tell us anything - just like the sight will not give all the information to a dog.
Simply put, a person uses the sense of smell to determine the very presence of a thing. The item is then visually identified.
Dogs do the opposite: seeing an interesting object, the dog will begin to sniff it and only through the sense of smell will understand all the details.

The myth about monochrome vision of dogs is also spread. A team of scientists led by Dr. Jay Neitz has proven that dogs see color, they just do not perceive it as intensely as humans.
Dogs are color blind, they cannot accurately distinguish between red and green. But this does not prevent us from loving them!
