Dead On – Relentless II (1992)
Animal Action

A hotel cleaning woman keeps her large dog with her for protection. As they enter a room, they interrupt a murder in progress. The dog attacks the murderer and in the struggle, the dog is thrown through a glass window, presumably to his death many floors below. (The long fall and landing is not shown on film.) An American Humane representative was present for both the training and filming of this scene. The dog had been trained to jump up and then off a seven-foot wall, and also prepped to go through candy glass. He was also trained to attack and release on command. For the actual filming, the scene was shot in numerous cuts and edited together later. Although the window appeared to be high, the dog landed just below the sill, out of camera range.
