Ever wonder why dogs circle so much before pooing? Fido is measuring the direction of the localized magnetic field.
The ritual DOES have a purpose. Fido's aligning with the local flux, he changes the body angle with the local declination, so not a North heading compass as we know it.
They show a trend to b aligned North/South and avoid a East/West orientation.
The statistics show a significant positive correlation.
