The video shows a cartoon dog with a pink body and a long snout. The dog is seen peeking out from under a door with its paws and then suddenly jumps out with a surprised expression. The dog's eyes are wide and its mouth is open. The dog then proceeds to chase a small blue mouse with white paws and a long tail. The dog's movements are exaggerated and comical as it tries to catch the mouse. The background is a simple brown door and beige floor.
