“It as true that normal people couldn't hear Gaspode speak, because dogs don't speak. It's a well know fact....Besides, almost all dogs don't talk. Ones that do are merely a statistical error, and can therefore be ignored.”

“Only Ron's dog was watching William. He considered that it had, for a dog, a very offensive and knowing look.A couple of months ago someaone had tried to hand William the old story about there being a dog in the city that could talk. (...) The dog in front of William didn't look as if it could talk, but it DID look as if it would swear.”

“William groaned. It was Vimes. Worse, he was smiling, in a humourless predatory way."Ah, Mr de Worde," he said, stepping inside. "There are several thousand dogs stampeding through the city at the moment. This is an interesting fact, isn't it?"He leaned against the wall and produced a cigar. "Well, I say dogs," he said, striking a match on Goodmountain's helmet. "Mostly dogs, perhaps I should say. Some cats. More cats now, in fact, 'cos, hah, there's nothing like a, yes, a tidal wave of dogs, fighting and biting and howling, to sort of, how can I put it, give a city a certain . . . busyness. Especially underfoot,because - did I mention it? -they're very nervous dogs too. Oh, and did I mention cattle?" he went on, conversationally. "You know how it is, market day and so on, people are driving the cows and, my goodness, around the corner comes a wall of wailing dogs . . . Oh, and I forgot about the sheep. And the chickens, although I imagine there's not much left of the chickens now.”

“Dogs are not like cats, who amusingly tolerate humans only until someone comes up with a tin opener that can be operated with a paw. Men made dogs, they took wolves and gave them human things--unnecessary intelligence, names, a desire to belong, and a twitching inferiority complex. All dogs dream wolf dreams, and know they're dreaming of biting their Maker. Every dog knows, deep in his heart, that he is a Bad Dog...”

“The universe contains any amount of horrible ways to be woken up, such as the noise of the mob breaking down the front door, the scream of fire engines, or the realization that today is the Monday which on Friday night was a comfortably long way off. A dog's wet nose is not strictly speaking the worst of the bunch, but it has its own peculiar dreadfulness which connoisseurs of the ghastly and dog owners everywhere have come to know and dread. It's like having a small piece of defrosting liver pressed lovingly against you.”

“People don't like change. But make the change fast enough and you go from one type of normal to another.”

“You can't go around building a better world for people. Only people can build a better world for people. Otherwise it's just a cage. Besides you don't build a better world by choppin' heads off and giving decent girls away to frogs.”
