    Dogs shit in alignment with the Earth's magnetic field. Don't say I never contribute...

    Frontiers in Zoology | Abstract | Dogs are sensitive to small variations of the Earth's magnetic field

    Introduction
    Several mammalian species spontaneously align their body axis with respect to the Earth's magnetic field (MF) lines in diverse behavioral contexts. Magnetic alignment is a suitable paradigm to scan for the occurrence of magnetosensitivity across animal taxa with the heuristic potential to contribute to the understanding of the mechanism of magnetoreception and identify further functions of magnetosensation apart from navigation. With this in mind we searched for signs of magnetic alignment in dogs. We measured the direction of the body axis in 70 dogs of 37 breeds during defecation (1,893 observations) and urination (5,582 observations) over a two-year period. After complete sampling, we sorted the data according to the geomagnetic conditions prevailing during the respective sampling periods. Relative declination and intensity changes of the MF during the respective dog walks were calculated from daily magnetograms. Directional preferences of dogs under different MF conditions were analyzed and tested by means of circular statistics.

    Results
    Dogs preferred to excrete with the body being aligned along the North-south axis under calm MF conditions. This directional behavior was abolished under Unstable MF. The best predictor of the behavioral switch was the rate of change in declination, i.e., polar orientation of the MF.

    Conclusions
    It is for the first time that (a) magnetic sensitivity was proved in dogs, (b) a measurable, predictable behavioral reaction upon natural MF fluctuations could be unambiguously proven in a mammal, and (c) high sensitivity to small changes in polarity, rather than in intensity, of MF was identified as biologically meaningful. Our findings open new horizons in magnetoreception research. Since the MF is calm in only about 20 % of the daylight period, our findings might provide an explanation why many magnetoreception experiments were hardly replicable and why directional values of records in diverse observations are frequently compromised by scatter.

    Now it makes sense why my dog spins (can be up to 4 times) in an anti-clockwise direction just before the excretion starts...

      he's like a smartphone. just calibrating himself.
      “Crashing is shit for you, shit for the bike, shit for the mechanics and shit for the set-up,” Checa told me a while back. “It’s a signal that you are heading in the wrong direction. You want to win but crashing is the opposite. It’s like being in France when you want to go to England and when you crash you go to Spain. That way you’ll never get to England!” -- Carlos Checa

        Mine tends to move upwind spin around a few times and point his arse at me, but I guess his consistency could be related to magnetic polarity, I thought he was just sharing.
        Do you remember the good old days before the internet?

        when arguments were only entered into by the physically or intellectually able.

          So do dogs turds curl around clockwise in the northern hemisphere and anticlockwise in the southern hemisphere?

            I'm going to feed my dog more red meat to see if i can make her a compass.

            If that work i am going to get a couple puppies, do the same and produce a strain of compass dogs for explorers.
