Sochi animal rescue organisations began bringing in dogs from the streets after reports that they were getting rounded up and poisoned circulated around the Games.
At the time, American skier Gus Kenworthy, an Olympic silver medalist, made headlines when he pledged to bring four street dogs back to the US after the February 7-23 Games.
Humane Society International worked both on Kenworthy's project and bringing these 10 dogs, all mixed breeds, to the US last week.
"They're the sweetest, most interactive, very friendly dogs, very adoptable that just happen to be unfortunate enough to be living on the street."

The group worked with PovoDog Animal Shelter in Sochi and two other organisations to arrange vaccination, documentation and travel for the dogs, who then spent two days in transit.
"These dogs have had a tremendous journey. It's been almost two days of travel for them. They went from Sochi to Moscow, had a long layover in Moscow, and then the flight to Dulles airport today," O'Meara was quoted as saying by CNN.
The dogs will be housed for the time being in the Washington Animal Rescue League facilities here.
Bob Ramin, CEO of the animal league, said the next few days are all about comfort for the animals.
"These animals are seeing a lot of new things and experiencing a lot of new things, so they're kind of stressed out," Ramin said. "We want to make sure they know they're in a safe place so we've got our staff working with them one on one."
Organisers say that they expect a great deal of interest in these dogs because the public outcry before, during and after the Games. More dogs are expected to arrive in the US for adoption in the coming days, the report said.
