Scientists in Moscow say stray dogs have learnt to use the subway to travel to the city centre in search of food.

Biology professor Andrew Poyarkov said he had seen several dogs unaccompanied on the city's underground rail system, reports rupor.org. He claims the dogs travel into the city centre, where they can more easily find food, each morning and travel back to where they live each evening.

"They do not just go to the subway station, they actually board the trains," he said. "They seem to have learnt 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 centre."

Dr Poyarkov said he had also noted the same dogs waiting for a green light to cross the road. He says they have somehow managed to pick up habits from humans and is investigating the phenomenon.

And it works the other way around. Isn't that how dogging started?


Eventually the underground was too much effort...
