Montmorency was an extremely mischievous dog whose highest ambition in life was to get in the way of everything and eventually get scolded and cursed for his troublesome acts.

He particularly got involved at the places where he was not wanted and became a ‘perfect nuisance’ making people go mad at him and resulting in things being thrown on his head. It is eventually the natural and original sin with which he is born makes him do such things, as the author says, stands perfectly true of Montmorency whose conceit becomes quite unbearable after accomplishing his funny business.
