The beloved pet of Lord Havelock Vetinari, the Patrician of Ankh-Morpork, Wuffles first appears as a terrible smell beneath Vetinari's desk, but turns out to breathe and move. Wuffles is a terrier about sixteens years of age. Witnessing the kidnapping of Vetinari and substitution of lookalike Charlie, Wuffles smells the differences and bits the perpetrators on the Ankle. A crossbow bolt fired at him misses and lodges in the carpet, forming prime evidence. Wuffles flees the Palace in the safety of Foul Ole Ron's stinking coat and avoids being captured by criminals of the Watch. He eventually tells his story to protagonist William de Worde for publication in the Ankh-Morpork Times.
