Godzilla: King of the Monsters (2019)

In the scene where the actor sneaks up on a female wolf and her pups eating a deer carcass, the wolf and her pups were brought to the set in crates inside a van that was driven to the field where they filmed. A hot wire was placed around the area where the wolves were working. The wolves were placed inside the hot wired area. Production filmed each wolf separately before they put the deer with food in it inside the pen. The deer was created by the props department. Prior to shooting they placed pieces of meat and chicken inside the fake deer. When they called action, the wolves ate the meat inside the deer.
