Zoologists are studying stray dogs in Moscow, and the ways they've adapted to city life:
Back in the lean Soviet era, restaurants and the now-ubiquitous fast-food kiosks were scarce, so dogs were less likely to beg and more likely to forage through garbage, the zoologists say. Foraging dogs prospered best in the vast industrial zones of Moscow, where they lived a semiferal existence. Because they mainly relied on people to throw out food, and less on handouts, they kept their distance from humans.
Now, old factories are being transformed into shopping centers and apartment blocks, so strays have become more avid and skillful beggars. They have developed innovative strategies, zoologists say, such as a come-from-behind ambush technique: A big dog pads up silently behind a man eating on the street and barks. The startled man drops his food. The dog eats it.
Key is the ability to determine which humans are most likely to be startled enough to drop their food. Strays have become master psychologists, says Andrei Poyarkov, 54, the dean of Moscow's stray-dog researchers. "The dogs know Muscovites better than Muscovites know the dogs."
