Sonic the Hedgehog 3 (2025)

In the scene where the dog sits with the family in a campsite, dog was walked to set on leash by the trainers. The set was a campsite in a fake forest constructed within a studio stage. The trainer cued the dog to lie on the grass between the two actors using hand and vocal gestures then stood off camera, within eyesight of the dog. The trainer moved in different positions to avoid the camera, which swiveled in different directions.
The actress said some lines and then both yelled surprise. After they cut camera they brought dog back to its holding area.

In the scene where a helicopter ascends and the dog is in his dog bed and reacts, trainers brought dog to set and trained him to get into bed when asked him to lie down. On action, the trainer cued dog to look down, as if reacting to the helicopter.

When the actors in the basement see a rat scurry off on a ledge, the rat was carried to set by the trainer in a carry box. The trainer brought the rat in a catch box containing a buzzer; a piece of grain was placed at one end of a ledge. The halter crouched behind the box. When the camera was ready, the trainer placed the rat at the opposite end of the ledge. The trainer placed a small piece of grain on the ledge and placed the rat beside it. Once the rat had eaten the grain, the handler activated the buzzer in the catch box. The rat scurried along the ledge to the catch box. The handler behind the box quietly closed the box. The set was illuminated by flashlights. To reset the trainer stepped in and took the rat out of the catch box and placed a fresh piece of grain in the catch box. Once the shot the shot was done the rat was placed back into his carry box.

In the scene where the actors sit on a couch in the living room and we see the dog in the little bed in the side, trainers brought dog to set and placed him in bed. On action, the trainer cued dog to stay in bed.
