A quote attributed to radio frequency engineer Stanley Leinwoll reads, "No animal I know of can consistently be more of a friend and companion than a dog." This video, which tells the story of a stray mutt named Xiao Sa, is proof of this. Xiao Sa ran over 1700 kilometers with a group of cyclists after they tossed her a drumstick on their way to Tibet. The cute pup conquered 12 mountains, running up to 60 kilometers every day to keep stride with her new friends. Watch the video below to learn more about this inspiring dog’s adventure!
