Management of a Florida zoo said a young African painted dog was killed when a gate collapsed on her.

Zoo Miami posted on Facebook that the juvenile female lost it life Monday. She was one of five puppies born at the zoo in January.

Zoo officials say the endangered canines were being moved between enclosures in a routine transfer when a cable that supported a solid metal guillotine door separated, allowing the door to fall on the animal and to kill her instantly.

Officials say they’re investigating to determine the exact cause of the failure, which includes careful inspections of all similar equipment throughout the zoo.
