SIOUX CITY, Iowa - GOOD DOG!

Lots of pups can run and fetch a stick, or jump off a dock into the lake, but an Australian Shepherd named Secret prefers her fun on the frozen side. Secret, who calls Sioux City, Iowa home, loves to go sledding. That's cool, right?

Well, the great thing about this dog is that once she's down at the bottom of the hill, she grabs the sled in her teeth and pulls it up the hill to make another run.

Her owner says after a recent snowfall, Secret went up and down about 50 times.
