Ecology of the canine subway

Here’s an interesting Financial Times article on the ecology of stray dogs in Moscow:

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.

Those that remain most comfortable with people Poyarkov calls “guard dogs”. Their territories tend to be garages, warehouses, hospitals and other fenced-in institutions, and they develop ties to the security guards from whom they receive food and whom they regard as masters. I’ve seen them in my neighbourhood near the front gate to the Central Clinical Hospital for Civil Aviation. When I pass on the other side with my dog they cross the street towards us, barking loudly.


The beggars live in relatively small packs and are subordinate to leaders. If a dog is intelligent but occupies a low rank and does not get enough to eat, he will separate from the pack frequently to look for food. If he sees other dogs begging, he will watch and learn.

The third group comprises dogs that are somewhat socialised to people, but whose social interaction is directed almost exclusively towards other strays. Their main strategy for acquiring food is gathering scraps from the streets and the many open rubbish bins. During the Soviet period, the pickings were slim, which limited their population (as did a government policy of catching and killing them). But as Russia began to prosper in the post-Soviet years, official efforts to cull them fell away and, at the same time, many more choice offerings appeared in the bins. The strays flourished.

The last of Poyarkov’s groups are the wild dogs. “There are dogs living in the city that are not socialised to people. They know people, but view them as dangerous. Their range is extremely broad, and they are ­predators. They catch mice, rats and the occasional cat. They live in the city, but as a rule near industrial complexes, or in wooded parks. They are nocturnal and walk about when there are fewer people on the streets.”

It’s an interesting story of what happens when a domesticated animal is, in a sense, redomesticated, or undomesticated. These dogs have also learned how to use the subway system to get from place to place. Surely that is a novel behavior you wouldn’t expect from animal psychology? What’s interesting is that not all the dogs have learned how to do this but, presumably, are able to pass on the ability to other dogs who follow them. Do we have a little animal culture here?
