I've always seen Carol (and I can't remember her last name) in freestyle competition videos with her Golden to Grease music. This is a really cool one with a guy and his border collie.

That's wonderful! I've never seen anything like that before.

THat is so cool. They put a lot of time into that routine. My son thought it was hilarious.
