Final answer:
In George Orwell's Animal Farm, the dogs symbolize the Soviet secret police, enforcing Napoleon's rule through intimidation and violence.
Step-by-step explanation:
The dogs in the excerpt from Animal Farm by George Orwell allude to the Soviet secret police, known as the NKVD. These enforcers were feared during Stalin's reign, conducting mass arrests, show trials, and executing or deporting millions to labor camps. Orwell's portrayal of the dogs as loyal enforcers of Napoleon's will reflects the coercive methods used by the secret police to maintain the Soviet leader's power and control.
