Dogs cannot see color, so I do not think it will matter very much...Extensive scientific testing on dogs supports the conclusion that they live in a colorless world. The testing done primarily focussed on the dogs' responses to colors for food. Dogs could not tell the difference between one color, a signal for food, and other colors, that were not for food. Similar tests conducted on cats produced similar results, which led scientists to conclude that they, too, are colorblind and live in a gray world. |
