As a man who thinks he understands how the world works, I'm not at all surprised to see dogs on a plethora of tobacco tin art. I'm also not surprised that there aren't a bunch of cats on tobacco tin art. There's a lot of good songs about dogs. Nobody writes good songs about cats. Nobody ever made a good film about a cat either. We could probably out-do the Secret Santa thread page count just by talking about good dog movies. Excellence in art requires an excellent subject, and as I believe I've clearly demonstrated, dogs are excellent.
