Weird science: Dogs have internal magnetic compass to guide pooping orientation

Cutting edge research Many animals behave in ways that show that they can use the Earth's magnetic fields to guide themselves. The most common examples of magnetic sensitivity are found in birds, which makes intuitive sense because birds often migrate over large distances. But now, for the first time, magnetic sensitivity has been shown in dogs, and the way that scientists discovered Fido's internal compass is a bit unusual. Researchers gathered data over two years by following 70 different dogs, from 37 different breeds, as they... defecated and urinated. 1,893 poops, and 5,582 urinations in all. That's dedication to science!READ MORE LINK-http://www.treehugger.com/natural-sciences/weird-science-dogs-have-internal-magnetic-compass-guide-pooping-orientation.html
