Walkies on two wheels
Opee the dog doesn't go for walkies, he prefers "ridies" on his owner's motocross bike.
Mike Schelin has trained the eight-year-old Australian shepherd to sit in front of him during dirt bike races in California – wearing his own helmet and goggles.
"This dog has been over 150 mph and absolutely loves it. He just looks like he's having a blast. The faster we go, the more fun he has," Mr Schelin said.
Mr Schelin added that he didn't like leaving his pet to go riding, and discovered Opee's need for speed when the dog leapt into the saddle one day.
