Energizer Bunny, Meet Energizer Dog

It just keeps going and going and going and going and going...You get the point! So this dog proves that some dogs have limitless amounts of energy.  I have a chocolate lab, and when she was a pup i really thought she would never stop.  She was constantly chewing up things, and the second you'd turn around she'd have something valuable of yours in her mouth wanting you to chase after her before she devoured it.   Now my dog has grown up, she's 6, and she's not as full of energy as she used to be, she still gets her energy bursts, but not nearly like when she was a pup.  But that happens, when your energetic pup turns into a big lazy baby.  This dog however I don't think will ever slow down.  After his owner "cranks" his tail he spins around and around like a top.
