In the scene when police officers investigate a shed and a dog jumps and barks at an officer, the trainers brought two dogs to set. The animal handlers were brought into the shed to determine where the dog should be chained. It was decided that the dog would be chained to a sturdy post on the left side of the shed. Loose equipment was moved to the other side of the shed, so that there would be no equipment for the dog to knock over. On action, the trainer used an aggression sleeve and commanded the dog to "attack". The dog ran to the end of his chain and barked aggressively at the trainer. On action, the trainer cued the dog to attack with hand signals, and the dog barked aggressively at the actor. He was not touched by the actors who stood three feet in front of him out of reach. Everything went smoothly. The dog was rewarded with treats after shooting the scene.
