Last April I linked to an item about stray dogs in Moscow who commute to the city center.
The phenomenon of "commuting dogs" has drawn increasing scientific study.
Where did these animals come from? It’s a question Andrei Poyarkov, 56, a biologist specialising in wolves, has dedicated himself to answering. His research focuses on how different environments affect dogs’ behaviour and social organisation. About 30 years ago, he began studying Moscow’s stray dogs. Poyarkov contends that their appearance and behaviour have changed over the decades as they have continuously adapted to the changing face of Russia’s capital. Virtually all the city’s strays were born that way: dumping a pet dog on the streets of Moscow amounts to a near-certain death sentence. Poyarkov reckons fewer than 3 per cent survive.
