Seeing a dog riding the subway alone every day, an inquisitive passenger tracked him.
A Mystery
To all, the dog proved to be a bit of a riddle. He was not wearing a collar, hence nobody knew who to contact to acquire further details on him. Conversely, he looked to have an exceptional degree of training since he could leap from one train to another without direction. Every morning, he would show up at the metro station without fail, as if he had some significant locations to be at. He would behave as though his schedule was full of obligations. People felt terrible for the puppy even though they thought it was very cute and humorous as it was standing all by itself.
After some while, they started to worry that he was a stray looking for his owner. A few people even put posters of him on hope that someone would find their missing dog identified. Still, weeks passed and none of these posters attracted anyone.
