“When Napoleon seizes the nine dogs for himself, it’s one of the early signs of his corrupt intentions. He takes them from their parents, Jessie and Bluebell, shortly after they are born, saying that he would make himself responsible for their education, and then raising them in isolation from the rest of the farm (3.12).
The dogs do not reappear until tension between Napoleon and Snowball reaches a breaking point. After it appears that Snowball has won the crowd, Napoleon lets out a whistle; At this there was a terrible baying sound outside, and nine enormous dogs, wearing brass-studded collars came bounding into the barn (5.14). They drive Snowball off the farm. From this point on, the dogs are constantly with the pigs, intimidating and threatening the other animals to make sure that the pigs get their way. The narrator ironically notes, It was noticed that they wagged their tails to him [Napoleon] in the same way as the other dogs had been used to do to Mr. Jones
