George Orwell's controversial novel 'Animal Farm' deals with the rise and the eventual corruption of Communism. Every character/incident in the book represents things in history. Which type of animal in this book was considered the smartest and therefore the best leader?

In Animal Farm, the pigs represent the Bolshevik leadership and are portrayed as the most intelligent animals who organize the rebellion and eventually become the corrupt ruling class. They teach themselves to read and write, making them the natural leaders, while other animals like dogs (enforcers), sheep (blind followers), and cats (apathetic) serve different allegorical roles.
