Gobi: A Little Dog with a Big Heart (2017)

Gobi, a scrappy little stray dog, latches onto a man named Dion and keeps pace alongside him as he runs his way across China in a long 80-mile race. Through cold nights and raging rivers, with little food and water, and through a long, hard journey, these two create a bond unlike any other. Cross the finish line with Gobi and Dion, the little pup who never quit and the ultramarathon runner who loves her.
