Dogs are sensitive to small variations of the Earth’s magnetic field

In short:

Looked at the direction dogs faced when urinating to see if there was a link with earth’s magnetic field. When the field was calm there was a clear preference for being on the north-south axis!

Results:

Dogs preferred to excrete with the body being aligned along the North鈥揝outh 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.

Questions raised:

Shows that dogs like many other animals are sensitive to MF. To what extent are humans? Are there similar studies?

Insights, lessons learnt:

There are many surprising unknown things going on in day to day life, lots left to be discovered.

Highlights:

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.

Results: Dogs preferred to excrete with the body being aligned along the North鈥揝outh 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.
