Every White House family in the last century has housed a presidential pup — every White House, that is, except President Trump’s. More than a preference, perhaps it’s because no dog would have him. Trump has a habit of speaking ill of man’s best friend.

Most recently Trump said retiring Republican gadfly Sen. Bob Corker “couldn’t get elected dog catcher in Tennessee.” And at least 33 other times on Twitter, the president has used canine-inspired vocabulary to attack his enemies.
