KSDK – Next time you see a magnet, it wouldn't be too big of a stretch to think about dog poop.

If you've ever observed your dog in action, you might have noticed that it takes a while for Fido to find the optimal place to poop, often sniffing the ground, squatting, standing back up and changing positions before finding the sweet spot.

According to Czech researchers, your dog is being finicky because it prefers to do its business while "aligned along the north-south axis under calm [magnetic field] conditions."

That's right: the earth's magnetic field dictates how your dog poops.

And if the field is in the flux, "this directional behavior was abolished" – which might explain your dog's constant starting and stopping when he's looking for a place to poop.

This might seem ridiculous, but the researchers actually put a lot of work into the study. They observed more than 70 dogs going No. 2 over a two-year period (that amounts to 1,893 defecations and 5,582 urinations).
