Cats are already able to adjust the local gravitational constant.  Why should this be surprising?

Why do you think they change direction to poop?

This is interesting but TFA doesn't make clear whether the dogs truly oriented to magnetic North or just plain old geographic North.  North ain't North all over and especially as the North magnetic pole has moved a lot lately the distinction between the two seems important.

If this is true then my dog is a Juggalo.

I take my cat with me to visit my parents every weekend.  It is a 50 mile trip.  Lately, due to construction, I have to change my route.  Every time I use a different exit or turn on a different street, he gets up and looks around very confused.  He starts looking out the windows and goes back and forth from right to left and back.  The rest of the time, he just chills.  He also knows when we get within a mile of Grandma's house because he starts getting really excited.

well, it doesn't say it, but, it's right there in the headline

"Dogs may use Earth's magnetic field to navigate"

/geographical north does not have a magnetic field associated with it

And that's the point.  TFA says dogs line themselves up north-south, but depending on your longitude magnetic and geographic north may differ by quite a few degrees.  I wonder if the researchers took that into account.

Pixelette - he's a she.

Aright then.  Carry on.

Naw, more like he runs away and then once he's several miles away is all like "magnetic fields, how do they work!?" and then I have to drive around until I find him trying to romance some random neighborhood hussy.

Why would you think dogs have any notion of geographic north?

Geographic north is an entirely artificial human concept based on what we perceive as "up".

If that's the same Czech study on dogs and magnetic fields that I had to review for my animal bio class, the science is pretty iffy. I'd be curious to see the other studies.

when let loose, my dog poops downwind from its nose. i don't carry a compass.
if dogs can figure out north-south they then need the distance that they have traveled to get back.

i put more faith in a dogs nose than in a scientist any day.
"the dog found its way home"  could be, "it followed me back home"

i am still waiting for the husky that ran away to come back....it has been 36 years and nothing yet.
i am about to give up hope.
