Do dogs really see in only black and white?

We have probably all been told that dogs only see in black and white. Research by veterinarians shows that dogs do see colors; they just cannot distinguish as many colors as people do. This is probably because there are fewer cones in a dog's eye, the cones in the eye are used for color recognition. Even though dogs cannot distinguish as many colors as people do; their vision is far superior to ours in dim light, and they also detect motion better than people.
