Sophie Turner, who plays Sansa Stark, adopted Zunni, the Northern Inuit dog that played her pet direwolf on the series’ first season. “Growing up I always wanted a dog, but my parents never wanted one,” Turner told Coventry Telegraph in 2013. “We kind of fell in love with my character’s direwolf, Lady, on set.
