Au contraire...
that's what the study (70 dogs) was all about..
If you were to carefully measure your dog's position AND measure the
local magnetic field, you'd find that they are correlated, with a pretty
decent significance.
It's actually pretty interesting scientifically.
We know that birds have magnetic sensors.. And it's been theorized that
mammals do too, so this is actually a fairly inexpensive way to look at
it.. if you find out that there's some magnetic field correlation to
behavior, that's a telling sign that there must be some sensing mechanism.
What would be interesting is to make sure that they're not being cued by
some other factor (e.g. sun angles). If you keep dogs in a kennel with
Helmholz coils to change the magnetic field, for instance.
Or Northern vs Southern Hemisphere (sun in the south in Norther, sun in
the north in Southern.
