Katherine Heigl claims it's a ''miracle'' the puppies she rescued from Russia are alive.

The 35-year-old beauty helped bring two pooches called Sochi and Adler back to America after she realised how unwell they were during the Sochi Winter Olympics, but complications arose when the dogs were found to be suffering from life-threatening diseases during quarantine.

Katherine says they're doing well now and is surprised the dogs are still alive after the whole ordeal.

She explained on US chat show 'The Talk': ''It was really intense. I don't know if you watched the Olympics and saw what was going on over there with the animals, but it's equally as bad here.

''We were asked by the NSPCA to help with two puppies. We showed up at the airport and took these dogs.

''We thought the male dog was dead, he wasn't moving, we couldn't rouse him, and we drove immediately to the emergency vet.

''The other little puppy seemed to be in good health, but then she ended up having respiratory problems.''

Katherine showed off her new pets on the show and proudly announced: ''He was almost dead. It's a miracle he's alive.''
