What is the significant about the dogs wagging their tails at napoleon?

In George Orwell's "Animal Farm," the dogs wagging their tails at Napoleon symbolize their loyalty and submission to his authority. This behavior highlights the power dynamics on the farm, as the dogs represent the force that enforces Napoleon's rule and suppresses dissent. Their tail-wagging also reflects the manipulation of loyalty and fear, emphasizing how Propaganda and intimidation are used to maintain control over the other animals. Ultimately, it underscores the theme of corruption and betrayal in the pursuit of power.
