There may not be another tale of friendship as heartwarming as the story of Xiongxiong and his owner.

Xiongxiong, which is the Chinese word for "bear", is a dog who spends over 12 hours every day waiting at the train station for his owner to get back from work.

Xiongxiong's owner, a man who is identified as Mr. Chen, takes the train from the Liziba metro station in Chongqing's Yuzhong district of southwest China. Since Mr. Chen lives down the road, the 15-year-old dog will saunter down to the station every morning and plop down on the pavement for his 12-hour watch.

Because Xiongxiong is so well-behaved, he never has to wear a collar or leash.

While he does accept occasional head pets from strangers, he saves all of his energy for when Mr. Chen comes home.

In a video that is winning hearts all over the internet, Xiongxiong catches sight of Mr. Chen and transforms from a reserved senior canine into a jubilant puppy who is excited to see his owner. As the two of them walk home from the station, Xiongxiong can be seen wagging his tail, barking happily, and energetically trotting alongside his companion.

"I've had Xiongxiong for about seven or eight years," Mr. Chen told a Chinese news outlet. "Ever since I have had him, he has waited for me every day.

"He is always happy when he sees me, which makes me very happy too," he added. "Xiongxiong always manages to make me less tired from work."
