I think the dogs represent the Red Guards of USSR. Red Guards were defense force of the Bolsheviks and nine dogs protect pigs. "The Bolsheviks to set up a defense force called the Red Guards"(pg. 21 of Russia in War and Revolution) and Napoleon trained nine dogs to protect himself. ㅡSung-Woo Choㅡ

I also think that the dogs represented the Red Guards or the KGB- secret police. They were not really police but big supporters of Stalin and used force to control people. And when people did not listen to them, they would kill the opponents of Stalin. I thought that this really related to the roles of the dogs. - Connie H-
