Dog news: The real reason dogs always find their way home – breakthrough study | Science | News
Researchers are now convinced that this helped the dogs orientate themselves for the return journey.
In a summary of their results in the online journal eLife, the researchers write: “It is unlikely that the direct involvement of visual, olfactory or celestial cues can explain the highly stereotypical and consistent ~ north-south orientation of the compass course.
“For example, the wooded habitat and the dense vegetation of the study areas make visual piloting unreliable and in many cases not possible.”
After this first compass run, dogs worked their way back and relied on two special forms of navigation.
