In case you needed further proof that some dogs have limitless energy, a woman winds her dog up like a toy, then lets it loose in her backyard where it spins like an insane top.

The woman "cranks" the pug's tail, then places the revved up animal on the ground where it spins maniacally in tight circles for almost a minute.

The doggie tornado even stops and changes direction several times for good measure, eventually coming to a halt while looking proud, if a little woozy.

If only we could find a way to harness this crazy dog's power, all our energy worries would be solved.
