Song Hye Gyo and Im Se Mi volunteer at a shelter for dogs

Song Hye Gyo and fellow 'Wind Blows in Winter' co-star Im Se Mi have been spotted helping shelter dogs!

The volunteer group 'KARA' posted photos of the two actresses working at a house in Yeoju that sheltered dogs. The two stars dressed in blue work outfits and masks as well as caps to protect them from the sun. Along with the other volunteers, they helped clean up the shelter and take care of the dogs.

'KARA' wrote, "[Song Hye Gyo] is not just pretty on the outside, but on the inside as well... She worked hard until the end and did her best as she cleaned up trash, fed them snacks, groomed them, and threw away trash."

Currently, Song Hye Gyo is preparing for her upcoming Chinese movie.
