In the video, a person is seen opening a cage door with a dog inside. The dog is a large breed with a brown and white coat. As the door opens, the dog excitedly jumps out of the cage and starts running around. The person who opened the door is wearing a green shirt and is standing in a room with white walls. The cage is made of metal bars and has a green blanket inside. The dog seems to be happy and energetic as it runs around the room.
