Snowball and Napoleon fall out with each other, as they have different ideas for how Animal Farm should be led. Snowball announces plans to build a windmill, but Napoleon disagrees. Napoleon trains nine puppies, who grow into vicious dogs who will serve him. When the dogs are fully grown, he uses them to chase Snowball off the farm. He takes control and rules the farm by himself (as a dictator). Napoleon uses the dogs to kill any animal that does not agree with him, while a pig called Squealer keeps telling the animals that everything is fine and they should support Napoleon.
