Read the following paragraph and extract the answer for the question: What species is Sherman's father?  Mr. Peabody is a gifted anthropomorphic dog who lives in a penthouse in New York City and raises his adopted human son, 7-year-old Sherman, and tutors him travelling throughout history using the WABAC, a time machine. They visit Marie Antoinette in Versailles during the French Revolution in 1789. Getting caught in the Reign of Terror, Peabody is nearly sent to the guillotine to be executed by Maximilien Robespierre, but escapes with Sherman through the Paris sewers. In the present day, Sherman attends the Susan B. Anthony School on his first day of school. His knowledge of the apocryphal nature of the George Washington cherry-tree anecdote leads to a fight with one of his classmates, a girl named Penny Peterson, in the cafeteria where she treats him like a dog and puts him in a choke hold, humiliating him. Peabody is called in by Principal Purdy as Sherman had bit Penny in retaliation, and also confronted by Ms. Grunion, a Child Protective Services agent, who suspects that Sherman's behavior is due to being raised by a dog and plans to visit to their home to investigate whether he is an unfit parent. Peabody then invites Penny and her parents, Paul and Patty over for dinner to reconcile before Ms. Grunion arrives. Penny calls Sherman a liar for claiming first-hand knowledge of history. Despite Peabody's contrary instructions, Sherman shows Penny the WABAC to show proof and takes her into the past, where she stays in Ancient Egypt in 1332 BCE to marry King Tut. Sherman returns to get Mr. Peabody's help. Peabody hypnotises the Petersons and manages to retrieve Penny.
