Lassie is an American television series that follows the adventures of a female Rough Collie dog named Lassie and her companions, human and animal.

Fictional eleven-year-old Jeff Miller, his mother, and his grandfather are Lassie's first human companions until seven-year-old Timmy Martin and his adoptive parents take over in the fourth season. When Lassie's exploits on the farm end in the eleventh season, she finds new adventures in the wilderness with a succession of United States Forest Service Rangers. After traveling without human leads for a year, Lassie finally settles at a children's home for her final two syndicated seasons.Lassie received critical favor at its debut and won two Emmy Awards in its first years. Stars Jan Clayton and June Lockhart were nominated for Emmys. Merchandise produced during the show's run included books, a Halloween costume, clothing, toys, and other items.
