As he traverses the streets, he finds that all the dogs are alike, and that all are gaunt, hungry, half starved, savage, and cowardly, more like wolves than dogs, and quite as ready as wolves to attack when they fancy they can do so with safety. They prowl about the streets in great numbers, living, as they best can, on any scraps of food that they may happen to find. They have no particular masters, and no particular homes. Charitable persons will sometimes feed them, but will never make companions of them, feeling that the very contact of a dog would be a pollution. They are certainly useful animals, because they act as scavengers, and will eat almost any animal substance that comes in their way. The strangest part of their character is the organization which prevails among them. By some extraordinary means they divide the town into districts, and not one dog ever ventures out of that particular district to which it is attached. The boundaries, although invisible, are as effectual as the loftiest walls, and not even the daintiest morsel will tempt a dog to pass the mysterious line which forms the boundary of his district. Generally, these bands of dogs are so savage that any one who is obliged to walk in a district where the dogs do not know him is forced to carry a stout stick for his protection. Like their European relatives, they have great dislike towards persons who are dressed after a fashion to which they are unaccustomed, and therefore are sure to harass any one who comes from Europe and wears the costume of his own country. As is customary among animals which unite themselves in troops, each band is under the command of a single leader, whose position is recognised and his authority acknowledged by all the members. These peculiarities are to be seen almost exclusively in the dogs which run wild about the towns, because there is abundant evidence in the Scriptures that the animal was used in a partially domesticated state, certainly for the protection of their herds, and possibly for the guardianship of their houses. That the Dog was employed for the first of these purposes is shown in Job xxx. 1: "But now they that are younger than I have me in derision, whose fathers I would have disdained to have set with the dogs of my flock." And that the animal was used for the protection of houses is thought by some commentators to be shown by the well-known passage in Is. lvi. 10: "His watchmen are blind: they are all ignorant, they are all dumb dogs, they cannot bark; sleeping, lying down, loving to slumber." Still, it is very probable that in this passage the reference is not made to houses, but to the flocks and herds which these watchmen ought to have guarded.
