'Researchers from Czech University and the University of Duisburg-Essen in Germany observed 70 dogs from 37 different breeds over the course of a two-year period.
'They found that dogs preferred to excrete when their body was aligned along the north-south axis under "calm Earth's magnetic field (MF) conditions." '

The scientists' breakthrough may be difficult to replicate without high technology however, as calm Magnetic Field conditions only occur one fifth of the time, and dogs only do the doozey in line with the poles when the magnetic field is calm. That means your dog might not be a replacement for your compass after all.
