The story is narrated by a yellow dog who lives in New York. The yellow dog recounts his life, his owners, and his love for his master (and his dislike for his master's wife). Man and dog really do have a stronger bond in this story than man and wife, and 'Memoirs of a Yellow Dog' is a classic short story about our four-legged friends. O. Henry's short stories are well known for their wit, wordplay, warm characterization and clever twist endings.
