A forty-year-old man named Dmitri Gurov is intrigued by a young woman walking along the sea front of Yalta with her small Pomeranian dog. Dmitri dislikes his shrewish and intelligent wife and, as a result, has numerous love affairs. Although the protagonist disparages women and calls them "the lower race," he secretly acknowledges that he is more at ease in their company than in men's. One day, "the lady with the dog" sits down next to Dmitri to eat in the public gardens. The man pets her dog in order to strike up a conversation. He learns that she is called Anna Sergeyevna, that she is married, and that she has come to Yalta on vacation. Over the next week, Anna and Dmitri see a lot of each other and grow close. The older man is intrigued by the exuberant naïveté of his young partner, yet he also recognizes a trace of sadness in her character. In contrast to the elder women with whom he used to have affairs and who would occasionally display a "rapacious expression" on their beautiful faces, Anna excites Dmitri's desire with her fresh and unaffected nature. In particular, he is drawn by her "diffidence, the angularity of inexperienced youth" that reminds him of his daughter. Every evening the couple observes the sunset from the vantage point over Yalta at Oreanda and are impressed anew by the "beautiful and majestic" scenery. The only things that mar Anna's happiness is the thought that her husband, Von Diderits, will send for her and her fear that she has lost Dmitri's respect by sleeping with him. In the end, Von Diderits sends Anna a letter urging her return, and she leaves Dmitri with something like relief. When parting with Dmitri, Anna states, "It's a good thing I am going away … It's fate itself!
