Over the next several weeks I’ll tell you my thoughts about dogs’s senses:
There is no absolute scientific study of which I am aware indicating that dogs see color. Their world is black and white, and maybe shades of grey; therefore they see better than humans in dimly lit space. It is interesting that dogs recognize movement at a much greater distance than humans, yet the human eye maintains focus at a much greater distance then dogs. Depending on the breed, some dogs see further than others and some discern moving objects better than others. Many dogs respond as well to signals as verbal commands. (On many occasions I have noticed my dogs’ blank stare into the fields where deer roamed. It was only by a concentrated effort that I could distinguish the movement that he so easily recognized.)
