Task: Question Answering
Input (English): Passage: In 1630s New England, English settler William and his family — wife Katherine, daughter Thomasin, son Caleb, and fraternal twins Mercy and Jonas — are banished from a Puritan Plymouth Colony over a religious dispute. They build a farm near a large, secluded forest and Katherine has a newborn child, Samuel. One day, Thomasin is playing peekaboo with Samuel when the baby abruptly disappears. It is revealed that a witch had stolen the unbaptized Samuel and that night kills him and uses his blood and fat to make a flying ointment.Katherine, devastated, spends her days crying and praying, while William insists a wolf stole the baby. Even though Katherine forbids the children going to the forest, William takes Caleb to lay a trap for food. Caleb asks if Samuel's unbaptized soul will reach Heaven. William chastises Caleb for raising the question and later reveals to Caleb that he traded Katherine's silver cup for hunting supplies. That night, Katherine questions Thomasin about the disappearance of her cup while implying Thomasin was responsible for Samuel's vanishing. After the children retire to bed, they overhear their parents discussing sending Thomasin away to serve another family.
Early the next morning, Thomasin finds Caleb preparing to check the trap in the forest. She forces Caleb to take her with him by threatening to awaken their parents. While walking in the woods, they spot a hare, which sends their horse Burt into a panic and their dog Fowler promptly chases. Caleb runs off after the pair, while the horse throws Thomasin off, knocking her unconscious. Caleb becomes lost in the woods and stumbles upon Fowler's disemboweled body. As he gets deeper into the woods, he comes across a hovel, where a beautiful young woman emerges and seduces him. William finds Thomasin and takes her home. Katherine angrily chastises Thomasin for taking Caleb into the woods and, to save Thomasin, William reluctantly admits that he sold Katherine's silver cup. 
Question: What is the name of the family pet that chases the rabbit?
Output (English): Fowler.
