At this there was a terrible baying sound outside, and nine enormous dogs wearing brass-studded collars came bounding into the barn. They dashed straight for Snowball, who only sprang from his place just in time to escape their snapping jaws.
“If you have your lower animals to contend with,” he said, “we have our lower classes!” (Mr. Pilkington)
The birds did not understand Snowball's long words, but they accepted his explanation, and all the humbler animals set to work to learn the new maxim by heart. FOUR LEGS GOOD, TWO LEGS BAD, was inscribed on the end wall of the barn, above the Seven Commandments and in bigger letters.
Once again the animals were conscious of a vague uneasiness. Never to have any dealings with human beings, never to engage in trade, never to make use of money– had not these been among the earliest resolutions passed at that first triumphant Meeting after Jones was expelled? All the animals remembered passing such resolutions: or at least they thought that they remembered it. The four young pigs who had protested when Napoleon abolished the Meetings raised their voices timidly, but they were promptly silenced by a tremendous growling from the dogs. Then, as usual, the sheep broke into "Four legs good, two legs bad!" and the momentary awkwardness was smoothed over.
