Who are the nine dogs that suddenly appear in animal farm?

In George Orwell's "Animal Farm," the nine dogs that suddenly appear are the puppies raised by Napoleon to serve as his enforcers. They are trained to be loyal solely to him, embodying the tyrannical control he exerts over the other animals. These dogs play a crucial role in maintaining Napoleon's power, intimidating dissenters and ensuring obedience among the farm's inhabitants. Their presence symbolizes the use of violence and fear in totalitarian regimes.
