In Animal Farm, the pigs and dogs now sit on a raised platform at their Sunday Meetings. How is this symbolic of a dictatorship forming?

In this situation, we will follow the allegory through to
the symbols in the novel. The pigs would represent a group rising in power and the dogs
would represent the hired force to keep the people in control. Whenever a dictator comes
to power, he generally has to do so by force. The dogs being on the platform with the
dogs represent the fact that the pigs have a protective group ready to defend them in
case of revolt. Usually when people see an injustice like the rise of a dictator, at
least some will question. If enough question, a revolution will begin, and an attempt to
dethrone the ruling dictator will ensue.
