Pooping in Alignment with the Earth's Magnetic Field?

Yes, according to this article, researchers have discovered dogs tend to align themselves with the earth's magnetic field when they go potty.  After watching 70 dogs poop a grand total of 1,893 times, they determined that dogs prefer to align themselves in a north-south position for eliminating.

So after I read that article, I paid attention to Isaac when he went potty for the rest of the day.  He peed three times, all aligned in an east-west position.  However, he pooped once and did position himself north-south for that.

I told him he was peeing incorrectly but he did not seem concerned.
