In chapter 10 of George Orwell’s Animal Farm the animals witness a spectacle that amazes them. For some time the pigs have been engaged in violating the commandments of Animalism, and in the process they have begun to deal with humans and to act more and more human themselves.
The animals are returning from work when they see a pig walking on his hind legs, like a human being. The first pig is Squealer, then . . .
. . . a moment later, out from the door of the farmhouse came a long file of pigs, all walking on their hind legs.
Finally, Napoleon appears. The text does not state that Napoleon was preceded by dogs, but that as he walked, the dogs were “gambolling round him.” So it would be accurate to say that he was accompanied by dogs, but not preceded by them.
