.....Dogs poop in alignment with Earth's magnetic field, study finds.
Dogs use the Earth's magnetic field when they're relieving themselves. Not only that, but canines choose to do so in a north-south axis, a new study published in the journal Frontiers in Zoology says.

Several mammalian species spontaneously align their body axis with respect to the Earth’s
magnetic field (MF) lines in diverse behavioral contexts. Magnetic alignment is a suitable
paradigm to scan for the occurrence of magnetosensitivity across animal taxa with the
heuristic potential to contribute to the understanding of the mechanism of magnetoreception
and identify further functions of magnetosensation apart from navigation. With this in mind
we searched for signs of magnetic alignment in dogs. We measured the direction of the body
axis in 70 dogs of 37 breeds during defecation (1,893 observations) and urination (5,582
observations) over a two-year period. After complete sampling, we sorted the data according
to the geomagnetic conditions prevailing during the respective sampling periods. Relative
declination and intensity changes of the MF during the respective dog walks were calculated
from daily magnetograms. Directional preferences of dogs under different MF conditions
were analyzed and tested by means of circular statistics.
Results
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.
