A team of researchers from Czech University of Life Science<\/a>s, Virginia Tech and Barry University has found evidence that suggests dogs may use Earth’s magnetic field as a navigational aid. In their paper in the eLife Sciences<\/i> initiative, the group describes their study of dog navigation and what they learned from it.<\/p>\n

\n <\/section>\n

Prior research has shown that dogs tend to orient themselves in a north-south position when urinating\u2014a finding that suggests they may have the ability to sense the Earth’s magnetic field. In this new effort, the researchers conducted two experiments to further study magnetic field sensing in dogs and whether they use it for navigation.<\/p>\n

The two experiments were essentially the same\u2014they both involved attaching GPS sensors to multiple dogs, taking them out into a natural environment and releasing to run about. In all cases, the dogs soon returned to the person who had released them. The only difference in the experiments was the number of dogs involved\u2014in the first, it was just four, and in the second it was 27.
\nIn studying the routes the dogs took, both when heading out on an expedition and when returning, the researchers found they used one of two types of return. The first was called tracking, which meant a dog made its way back by following the same path it had taken out\u2014presumably using its nose. The team called the other type of return scouting\u2014because the dogs followed an unfamiliar path to get back to where they had begun their adventure. The researchers also found something else\u2014for a large percentage of the scouting returns, the dogs first engaged in an odd behavior. They ran north-south along a 20-meter length a few times before heading back to their starting point\u2014doing so app<\/a>eared to help the dogs get their bearings, as those that did it were more efficient in their return.
\nThe researchers suggest the north-south running is evidence of the dogs using the magnetic field to orient themselves in unfamiliar surroundings, which in turn helps them find their way home. Further testing involved the owner hiding as the dog made its trek, testing wind direction and speed and noting the gender of the dog. No other factors made a difference in improving navigational efficiency, further supporting the idea that the dogs were able to use the Earth’s magnetic field to navigate.<\/p>\n
