>"The devoted dog of Montargis avenges the death of his master, foully murdered in the Forest of Bondy; and a humorous Peasant with a red nose and a very little hat, whom I take from this hour forth to my bosom as a friend (I think he was a Waiter or an Hostler at a village Inn, but many years have passed since he and I have met), remarks that the sassigassity of that dog is indeed surprising; and evermore this jocular conceit will live in my remembrance fresh and unfading, overtopping all possible jokes, unto the end of time."

Surely the joke is the peasant's mispronunciation of "sagacity"? Also an odd Baader-Meinhoff, that story about the dog was on the front of reddit last week.
