Some experts say that dogs' sense of smell and hearing are too sensitive, which may lead to poor other sensory systems of dogs. Because the brain capacity of an animal directly determines the overall "system performance", if during long-term evolution, an animal uses a lot of "system resources" in hearing and smelling, then the resources it can use in other areas will be very limited. It is very likely that cats and dogs can process visual images not much faster than humans. The images played on TV are also continuous for them, so it is not strange for them to watch TV.
But it has also been suggested that, except for humans and many other primates, most mammals, including dogs, have only two types of rod cells. So when a beam of light hits the human eye, the human's color vision comes from three different signals, while the dog only has two different signals. The dimension of change is one less, and the colors perceived are fewer. It is difficult for dogs to distinguish between green, chartreuse, yellow and red, which is roughly equivalent to red-green color blindness in humans. Therefore, in its eyes, the colorful TV is a piece of gray. Are they really interested in these gray images? That's the question.
