Perhaps dogs in the southern Hemisphere spin clockwise?
Sorry to foil your hypothesis- I, too live in the Northern hemisphere.
Unfortunatly I spin clockwise, and am also from the southern hemisphere. I have to admit that I didn't take this seriously at first but now I have to say that spinning counter-clockwise feels really wrong.
He can even do his top act on the end of the couch, w/o stepping on me and w/o falling off. He's quite talented.
They are. Most mammals are left or right dominant and, like humans, they tend to favour righties by quite a bit, and in a similar proportion to the human lefty/right divide. There are apparently some exceptions though. Polar Bears are generally lefties. Useless trivia FTW!

Someone else mentioned hemispheres. I personally think it would be left or right dominance, like what foot we start out walking with or which way we turn over in bed.
I have German Shepherd bitch. She is now five years old, and I rescued her when she was three and a bit. She will turn either clockwise or anti-clockwise, randomly, on ANY occasion when she is about to settle down. I live North of the Equator. I have read suggestions that water runs down plug-holes, when baths are emptying, in different directions, North or South of the Equator, but I had not, before today, read any suggestions that dogs did something similar! Hilarious!
