In 2021, Istanbul’s public rail service spotted a curious passenger: “We noticed a dog using our metros and trains and he knows where to go,” spokesman Aylin Erol told India Today. “He knows where to get out. It’s like he has a purpose.”

The dog, known as Boji, is a stray Anatolian shepherd who’s been observed using the city’s buses, metro trains, trams, and ferries. Since city officials fitted him with a microchip, he’s been tracked through as many as 29 metro stations in one day, traveling up to 30 kilometers and ranging as far afield as the Princes’ Islands in the Sea of Marmara.

“You take the train and, suddenly, you see Boji,” Erol said. “And look at him. He lies, just like this. You just smile and catch the moment, really. This is what Boji evokes for Istanbulites. He also reminds us that we can still enjoy Istanbul as we rush about.”
