Here's another tradition that could fall by the wayside: the president-elect does not own a pet.

By the way, every year, Sept. 23 is designated National Dogs in Politics Day. That was the day in 1944 that Franklin D. Roosevelt mentioned Fala, his Scottish terrier, during a speech.

"These Republican leaders have not been content with attacks on me, or my wife, or on my sons. No, not content with that, they now include my little dog, Fala," Roosevelt told the International Brotherhood of Teamsters, Chauffeurs, Warehousemen and Helpers of America. "Well, of course, I don't resent attacks, and my family doesn't resent attacks, but Fala does resent them. You know, Fala is Scotch, and being a Scottie, as soon as he learned that the Republican fiction writers in Congress had concocted a story that I had left him behind on the Aleutian Islands and had sent a destroyer back to find him — at a cost to the taxpayers of two or three, or eight or twenty million dollars — his Scotch soul was furious. He has not been the same dog since."
