how did monts reney become a trouble for jerome? chapter 2

Montmorency had a problem staying out of trouble. 

But, when I had paid for about a dozen chickens that he had killed; and had dragged him, growling and kicking, by the scruff of his neck, out of a hundred and fourteen street fights; and had had a dead cat brought round for my inspection by an irate female, who called me a murderer; and had been summoned by the man next door but one for having a ferocious dog at large, that had kept him pinned up in his own tool-shed, afraid to venture his nose outside the door for over two hours on a cold night; and had learned that the gardener, unknown to myself, had won thirty shillings by backing him to kill rats against time, then I began to think that maybe they’d let him remain on earth for a bit longer, after all. To hang about a stable, and collect a gang of the most disreputable dogs to be found in the town, and lead them out to march round the slums to fight other disreputable dogs, is Montmorency’s idea of “life;” and so, as I before observed, he gave to the suggestion of inns, and pubs., and hotels his most emphatic approbation.
