The author uses a third-person limited narrator to reveal only the dog's feelings and instincts in the excerpt. This point of view allows the reader to gain insight into the dog's perspective, highlighting its fear and desire for warmth, which enhances the emotional depth of the story. Therefore, the correct answer would be:
The third-person omniscient narrator suggests the dog’s superior instincts.
(Note: While some of the options provided are not accurately phrased for third-person limited, a more fitting option would focus on the effectiveness of limited perspective in conveying the dog's thoughts and instincts.)
