Dogs preferred to excrete with the body being aligned along the North-south axis under calm MF conditions. This directional behavior was abolished under Unstable MF. The best predictor of the behavioral switch was the rate of change in declination, i.e., polar orientation of the MF.

Okay... yeah, that's an interesting bit of information, but when will science tackle the really big dog pooping preference question: Why do dogs insist on pooping directly under the clothes line no matter where in the yard said clothes line is located?
