The Dogs of Moscow

I came across an interesting animal article today, featured in several papers (this link to the Financial Times seemed the most comprehensive and reliable).  Wild and stray, roaming dogs have been a feature in Moscow since the 19th century, however through the generations they have begun to adapt to human's modern way of life.  They have pack life and roam the city for food, even using the subway (why walk when you can ride for free?) to find new sources of food.  They know which station they are at by smell and appearance. For the most part Moscovites live in acceptance of the dogs who help keep the city clean by catching mice, rats and eating up thrown away food.  Is it possible that the symbiotic relationship we once had with animals can work in a modern city?
