The terrier first showed an interest in extreme sports five years ago, when he leaped on JP's surfboard.
"Whenever we go near moving water, Part-X gets really, really excited," said JP.
Showing off his skills
"He even tries to bite the waves as we surf."
Part-X will soon be showing off his skills on a TV show called Dogs With Jobs.
He'll also be catching a few waves at Newquay Surf Festival this weekend.
