Racing to Save the Stray Dogs of Sochi

SOCHI, Russia — A dog shelter backed by a Russian billionaire is engaged in a frantic last-ditch effort to save hundreds of strays facing a death sentence before the Winter Olympics begin here.

Already, hundreds of animals have been killed, with the local authorities apparently wanting the stray dogs cleared from the streets before Friday’s opening ceremony.

While the authorities say the dogs can be wild and dangerous, reports of their systematic slaughter by a pest removal company hired by the government in recent months have outraged animal rights advocates and cast a gruesome specter over the traditionally cheery atmosphere of the Games.

The handling of the matter has also sharply undercut the image of a friendlier, welcoming Russia that President Vladimir V. Putin has sought to cultivate in recent months.
