It's a dog's life... but not for these strays.

They'd been happily roaming the Olympic Park in Sochi. That's until the authorities began to see them as a nuisance and threatened to have them put down.

But dog lover and Russian billionaire Oleg Deripaska has come to their rescue.

He's paying for this makeshift shelter where 140 dogs collected from the streets compete for people's affections. The top prize - becoming a pet.
