So sassy

A dog with a grey and white coat stands in a doorway, repeatedly peeking out from behind the door and then pulling back, its mouth open in a wide, exaggerated expression. The dog's head and body move rhythmically as it alternates between appearing and disappearing from view, creating a looping, playful peek-a-boo motion. The scene takes place indoors, with the dog positioned in a narrow hallway or room entrance.
