Runners in a 100-meter race in China were surprised when a stray dog joined the competition -- and nearly came in first.

A video filmed Thursday at the Beifang University of Nationalities in Yinchuan City, Ningxia Hui Autonomous Region, shows a white dog joining the human runners in the 100-meter event.

The video shows the canine finish second.

Witnesses said the dog is a stray that has been known to locals for more than four years.
