According to a team of German and Czech researchers, dogs have a particular sensitivity to magnetic fields, allowing them to move more easily. In other words, the dogs would possess a kind of internal compass. In reaching these conclusions, the research team investigating how the dog defecated.
In fact, researchers at the University of Duisburg-Essen, Germany, and University of studies Agricultural Prague, have found that the very dogs usually stop along a north-south axis to urinate or defecate, provided that the Earth’s magnetic field is stable at this moment.

All races combined

Some 7000 data collected by the dog owners have been scrutinized by researchers. Small Yorkshire big Saint Bernard, 70 dogs of various breeds have allowed the team to work. The latter found no difference in sensitivity to the magnetic field according to race, told AFP Sabine Begall, the German University.
To achieve the recently-published study by the English online journal Frontiers in Zoology (see site) – the team of ten researchers instructed 37 dog owners equipped with compasses to observe the behavior of their animals home when their needs.

Dogs feel magnetic fields

The purpose of this research? It helped to uncover the ability of dogs already have a smell and a powerful sound, to feel the magnetic fields. In 2008, this team of researchers had discovered, after studying images from Google Earth, tended the cattle to graze and lie along a north-south axis.

“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 field Earth’s magnetic, “said Ms. Begall.
