For dogs, we can imagine that their world is defined by their perception and action. Their perception includes being able to smell much more acutely than we can (including detecting changes in others’ hormones) and hearing within a greater range than we can. Thus, they will be able to respond to stimuli we don’t even notice. At another level, their umwelt is defined by the things they can bodily act on: They handle the world with their mouths, so the world gets divided into things-that-fit-in-the-mouth and things-that-don’t-fit-in-the-mouth—a way of seeing the world that is quite different than our own.......
