June Lockhart, best known for her roles in TV shows Lassie and Lost in Space, has died aged 100. The veteran actress died of natural causes at her home in Santa Monica on Thursday, a family spokesman told US media.

The actress had amassed more than 150 film and television credits during her career.

Like a real-life Lassie, Eeyore potentially saved his owner’s mother’s life. As the Okaloosa County Sheriff’s Office wrote in a statement, “It was a faithful four-legged friend who brought an OCSO deputy to her location.”
