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.
Terry PratchettOnly 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.
Terry Pratchett...William wondered why he always disliked people who said 'no offense meant.' Maybe it was because they found it easier to to say 'no offense meant' than actually to refrain from giving offense.
