Isn't that the same article that stated they watched a certain large breed of dog (I don't remember what breed) and it turned in circles until it aligned with an electromagnetic field before it pooped? I've been watching my 15-pound dogs and they run around in circles before they poop, too. They will squat with their butt facing north, south, east, or west and they're not feeling for the EMF. They are aligning their 'bomb' for an on-target delivery. lol
