Dog in Wikipedia
Dog. - The dog in the East does not enjoy the companionship and friendship of man as in the western countries. Its instinct has been cultivated only insofar as the protecting of the flocks and camps against wild animals is concerned. In the towns and villages it roams in the streets and places, of which it is the ordinary scavenger; packs of dogs in a half-wild state are met with in the cities and are not unfrequently dangerous for men. For this reason the dog has always been, and is still looked upon with loathing and aversion, as filthy and unclean. With a very few exceptions, whenever the dog is spoken of in the Bible (where it is mentioned over 40 times), it is with contempt, to remark either its voracious instincts, or its fierceness, or its loathsomeness; it was regarded as the emblem of lust, and of uncleanness in general. As some Muslims, to the present day, term Christians "dogs", so did the Jews of old apply that infamous name to Gentiles.
