Father Raymond J. de Souza: Who, exactly, are the dogs in Mayor Nenshi’s imagination?

Calgary Mayor Naheed Nenshi doesn’t like the dog whistles in the federal election campaign. Who is whistling and who are the dogs?

“Dog-whistle politics” is what they call it, and it is not a lovely term. It comes from the world of campaign consultants, and that is not a lovely world.

Dog whistles cannot be heard by ordinary people, as their ultrasonic waves are too high frequency for the human ear to detect. Dogs can hear them though, and so the dog whistle signals the dogs in a way that other people cannot hear.
