Dogs seem to have an awful lot of ritual before hunkering down and soiling the sidewalk. Its not uncommon to see a dog ownerplastic bag in handrolling his eyes as his furry companion sniffs and spins, getting just so before hunkering down to do the least considerate thing possible.
But for whatever its worth, all that spinning is far from arbitrary. What dog owners witness is a small and furry version of the aurora borealis and a link between species and environment thats as holistic and beautiful as a dog pooping can be. A team of Czech and German researchers found that dogs actually align themselves with the Earths magnetic field when they poop.
Proving at least that theyre really devoted to their work, the researchers measured the direction of the body axis of 70 dogs from 37 breeds during 1,893 defecations and 5,582 urinations over the course of two years, and found that dogs prefer to excrete with the body being aligned along the North-south axis under calm magnetic field conditions. They fittingly published their results in the journal Frontiers in Zoology.
You might wonder why dogs bother to do this, and uh, so do the researchers.
It is still enigmatic why the dogs do align at all, whether they do it consciously (i.e., whether the magnetic field is sensorial perceived (the dogs see, hear or smell the compass direction or perceive it as a haptic stimulus) or whether its reception is controlled on the vegetative level (they feel better/more comfortable or worse/less comfortable in a certain direction). Our analysis of the raw data (not shown here) indicates that dogs not only prefer N-S direction, but at the same time they also avoid E-W direction.
This isnt the only example of animals seemingly sensing the Earths magnetic field. Birds, turtles, and fish are known to use magnetic guidance while migrating. Cattle and deer are known to graze on a north-south axisas with defecating dogs, this is magnetic north, not the geographic one. Some bats navigate using a magnetic compass and given the large ranges of the dogs closest relatives in the wild, wolves, scientists suspected that canines might also sense the magnetic field.
But this was perhaps the first time that magnetic sensitivity was proven in dogs, and it was also the first time that a predictable behavioral reaction to the fluctuations in the magnetic fieldmagnetic storms, often as resulting from solar flareswas proven in a mammal.
If youre out walking your dog later, and he sidles up and pees on a tree facing east-west, dont be terribly surprised. The magnetic consciousness was observed only in dogs off leash, in the middle of a field. All things considered, the owner matters more to the dog than the Earths magnetic field; a nice little ego-booster that youll need as you bend over to pick up warm dog droppings.
