Scientists in Moscow say stray dogs have learned to use the subway to travel into the city’s center in search of food.
Biology professor Andrew Poyarkov said he has seen dogs exhibiting commuting behavior, as the dogs travel into the center of the city where they can more easily find food each morning, then travel back to where they live each evening.
According to Dr. Poyarkov, “They do not just go to the subway station, they actually board the trains. They seem to have learned how long they need to stay on the train to leave at the right station. Sometimes they fall asleep and miss their stop. Then they get off take another train back to the center.”
The dogs usually select the first or last car on the underground trains because these are usually the least crowded.
He also noted the same dogs crossing the street on a green traffic light, which investigating scientists feel has more to dog with the picture that appears on the light rather than the color.
Moscow ecologists believe that this behavior began in the early 1990s after the collapse of the Soviet Union and the rise of the new Russian capitalists. This commercial revolution eliminated many of Moscow’s industrial complexes and access to habitual feeding places like trash bins. This in turn forced the dogs to find new ways to reach different feeding grounds.
