I dont think Dogs have the cones in their eyes to detect colour They just have a very hi rez grey scale to see in the dark,or is it the rods they dont have?

They do however have a nose that is a quantum leap better than the nasal organ we taking Monkeys have in terms of sense of smell, and can probably smell the difference betwixt red and green.
