That's a lot of crap.
A study published this week in the journal Frontiers in Zoology suggests that dogs choose to relieve themselves along a north-south axis in line with Earths magnetic field. The Motherboard blog reported on the studys findings, saying that the research was carried out by a team of Czech and German scientists.
Dogs are sensitive to small variations of the Earths magnetic field, said the research team. Dogs preferred to excrete with the body being aligned along the North-south axis rather than the East-west axis.
The study examined the daily habits of 70 dogs during 1,893 defecations and 5,582 urinations over the course of two years. Consistently, during times of calm electromagnetic weather, the dogs chose to eliminate while facing north or south.
Dogs are not the only animals that are sensitive to the Earths magnetism. When it comes time for them to mate, salmon use their sense of the Earths magnetism to find their way back to the spawning grounds where they were born. Birds, similarly, migrate along magnetic lines. Even ants have been proven to have a sense of the Earths alignment and to distinguish between north, south, east and west.
As to why the dogs prefer to poop facing north or south rather than east or west, thats still a mystery.
That's a lot of crap.
