  Well, we can see old films that were just black and white okay! And plenty of people are also colour blind. We’re not quite sure what it looks like for a dog, but they do have better night vision than humans. And of course they have a great sense of smell and great hearing, which helps them to identify things around them.

  According to Google, dogs don’t see black and white, they’re just missing a part of the eye that responds to red light. So they see the same as us, except red things would be gray. Have a look for dog vision online and you can see what that looks like
