Dogs do in fact see in color, as shown by the fact that a dog's eye contains both rods (which we associate with B/W vision) and cones (which differentiate between colors). While humans' cones are attached to neurons that react to light at 435nm, 545nm and 570nm, a dog's cones react at 429nm and 555nm.
