"I moved to Moscow with my family last year and was startled to see so many stray dogs. Watching them over time, I realised that, despite some variation in colour – some were black, others yellowish white or russet – they all shared a certain look. They were medium-sized with thick fur, wedge-shaped heads and almond eyes. Their tails were long and their ears erect. They also acted differently. Every so often, you would see one waiting on a metro platform. When the train pulled up, the dog would step in, scramble up to lie on a seat or sit on the floor if the carriage was crowded, and then exit a few stops later. ...Neuronov says there are some 500 strays that live in the metro stations, especially during the colder months, but only about 20 have learned how to ride the trains. This happened gradually, first as a way to broaden their territory. Later, it became a way of life. “Why should they go by foot if they can move around by public transport?” he asks. “They orient themselves in a number of ways,” Neuronov adds. “They figure out where they are by smell, by recognising the name of the station from the recorded announcer’s voice and by time intervals. If, for example, you come every Monday and feed a dog, that dog will know when it’s Monday and the hour to expect you, based on their sense of time intervals from their ­biological clocks.”...The dogs divide into four types, he says, which are determined by their character, how they forage for food, their level of socialisation to people and the ecological niche they inhabit." - bob
