Ever wonder why frank take to get themselves into just the right position to do their business ? As it turns out , dogs array their body axis according to Earth ’s magnetic field when they scrunch to poop — a behavior that change when the charismatic field is fluid . But why do they do it ?
The resultant of this recently publish paper from Frontiers in Zoology auditory sensation goofy , but the takeaway is all in the title , “ Dogs are sensitive to low variations of the Earth ’s magnetic field . ”The researchers value the direction of the organic structure axis of 70 different dog while they were off - leash during 1,893 acts of defecation and 5,582 act of urination over a two - year menses . They found that , under calm magnetized field conditions , dog choose to orientate their bodies along the North - South axis when they poop . However , this behavior did not occur during unstable magnetized field conditions , and the unspoiled prognosticator for this change of conduct was the rate of change of magnetic declination .
This means that the hot dog are respond to changes in the polarity of the magnetized study rather than changes in intensity . It ’s that change in behavior that has the authors of this paper particularly excited , since it ’s the first time , according to the newspaper , that magnetic sensitivity has been proven in dogs and that a predictable behavioural reaction from natural magnetic theater of operations fluctuations has been unambiguously observed in mammal .

The question that this inevitably invites is : why on Earth do wiener do this ? The paper note that it ’s not just that dogs prefer to align themselves along the North - South axis ; they also seem to avert the East - West bloc when they poop , although it ’s not unmortgaged whether they do so consciously . The investigator propose that perhaps , when wiener poop , they are also taking the opportunity to point themselves :
An answer may lie in the biological signification of the behavior : if dogs would use a visual(radical - pair establish ) charismatic single-valued function to assist general preference in infinite as has been propose for rodents [ 32 ] , they might have the need to center on / graduate the map now and then with regardto landmarks or a magnetic denotation . Aligning the map and the opinion towards North ( orSouth ) facilitates reading the mapping . Furthermore , standardisation only makes sense when thereference is unchanging and reliable . We might cogitate of this the same way as a human being is stoppingduring a hike to take a map . When the mathematical function is smear or the reference ( comprehend magneticdirection ) is dispersed or moving due to magnetised disturbances , however , standardization isimpossible . In the case of the hotdog it thus would totally make sense to not pay aid tomagnetic body alignment any more under conditions of a shifting magnetic field .
