Well, not really. But watching this video made us wonder why we never even thought to ask.

The video, posted to Facebook last week, has earned nearly 3.5 million views and more than 14,000 shares.

It features a little girl in Oklahoma taking her cow for a walk — well, trot — with a toy tractor.

The cow runs right behind the little girl's tractor, until it decides it's had enough. When it stops in its tracks, the cow's strong enough to stop the little girl, too.

The exercise leaves the cow looking tired and the little girl proud. She looks straight to camera and flashes a big smile.
