TWITTER - This traffic-dodging pup is lighting up the internet in Mexico.

A biker with a Go Pro camera saw a little shih tzu with a leash running down avenida Revolución in Mexico City and tried to grab the dog to keep it out of traffic.

Little did the biker know the shih tzu had serious speed.

The biker chased the pup about 600 meters, or more than a third of a mile before a bystander eventually caught the dog by the leash, ending the epic run.

The daredevil dog put on some moves, rolling under a moving car and dodging plenty of others on its journey.

The biker, @calveritabike on Twitter, said the dog was returned to its owner.
