"after a cyclist gave her food during a cross-country race through China, Xiao Sa, a little stray dog with a really big heart, followed the cyclists 1,100 miles across very rough terrain.

The incredible journey of Xiao Sa began on the streets of Yajiang, Sichuan province. Zhang Heng, a 22-year-old student from Hubei, was on a graduation cycling trip to Lhasa, when he saw the small dog lying tired on the street. He and his friends stopped to feed her, and the pooch started following them."
