dogs have a compass in the body, according to a team of German and Czech researchers. She says that canines have a particular sensitivity to magnetic fields allowing them to move more easily. But the most curious is how the researchers came to this conclusion: they observed how dogs are placed for urinating or defecating

.

Indeed, they urinate or defecate, canines tend to stop along a north-south axis. To reach this conclusion published in the English newspaper online Frontiers in Zoology, a team of researchers from the University of Duisburg-Essen (northwest Germany) and the University of Agricultural Studies in Prague 37 responsible dog owners equipped with compasses to observe the behavior of their pets when their needs.

From small Yorkshire

big Saint Bernard, they sifted through 7000 data collected by the owners of 70 dogs of different breeds. And “we discovered that dogs stop along a north-south axis (a little more when they defecate when they urinate) but only if the magnetic field is stable” told AFP Sabine Begall of the University of Duisburg-Essen.

Thus, dogs are not only have a sense of smell and hearing a performance, but they can also feel magnetic fields. “It has been reported that dogs often travel hundreds of miles to find their way home. And the explanation for this is that they use to guide the Earth’s magnetic field” , concludes the researcher.
