    • n dog A quadruped of the genus Canis, C. familiaris. The origin of the dog is a question most difficult of solution. Some think the breed is derived from the wolf, others affirm it to be from a familiarized jackal; all agree that no trace of it is to be found in a primitive state, the dhole of India and the dingo of Australia being wild descendants from domesticated ancestors. The view now generally taken by naturalists is that the dog is neither a species, in the zoölogical sense, nor even the descendant of any one species modified by domestication, but that the dogs of different parts of the world have a correspondingly various ancestry, from different wild species of the genus Canis, as wolves, foxes, and jackals. This view is supported not only by the enormous differences between dogs, but also by the readiness with which nearly all dogs cross with their wild relatives; and, accordingly, the name Canis familiaris is a conventional rather than a proper zoölogical designation of the dog as a species. No satisfactory classification of the different kinds of dogs has been arrived at, what some naturalists regard as types being regarded by others as mere mongrels. An old classification grouped dogs in three classes, the Celeres, Sagaces, and Pugnaces. Colonel Hamilton Smith groups the domestic dog into six sections: the wolf-dogs, including the Siberian, Eskimo, Newfoundland, Great St. Bernard, sheep-dog, etc.; watch- and cattle-dogs, including the German boar-hound, Danish dog, dog of the North American Indians, etc.; the greyhounds, as the different kinds of greyhound, Irish hound, lurcher, Egyptian street-dog, etc.; the hounds, as the bloodhound, staghound, foxhound, harrier, beagle, pointer, setter, spaniel, springer, cocker, Blenheim dog, poodle, etc.; the curs, including the terrier and its allies; the mastiffs, including the different kinds of mastiff, bulldog, pug-dog, etc. All these are artificial varieties, having comparatively little stability, their distinctive characters being soon lost by reversion to a more generalized type if they are left to interbreed. This tendency to reversion requires to be constantly counteracted by “artificial selection” at the hands of breeders, in order that the several strains may be kept pure, and their peculiarities be perpetuated along the desired lines of specialization. The best-bred dogs, of whatever kind, are those furthest removed from an original or common type of structure. The differences between dogs of all kinds are vastly greater than those found among individuals of any species in a state of nature; so great that, were they not known to be artificial, the dog would represent several different genera of the family Canidœ in ordinary zoological classification. In fact, some genera, based upon actual and constant differences in the dental formula, have been named in order to signalize certain structural modifications which are found to exist, affording an example of the evolution of generic characters as well as of specific differences. These variations extend not only to size and general configuration, character of the pelage, and other outward features, but also to positive osteological and dental peculiarities, more marked probably than those of any other domesticated animals. The corresponding physiological and psychological differences are equally decided, as witnessed in the dispositions and temperaments of dogs, their comparative docility, intelligence, etc., and consequently the uses to which they are or may be put. In the matter of size alone, for example, some toy dogs are tiny enough to stand easily on one of the fore paws of a large dog. Throughout the endless varieties, however, the influence of heredity is witnessed in the readiness with which dogs interbreed with one another, and cross with wolves, foxes, and jackals, bearing fertile progeny in all cases, and the readiness with which they revert to the wild state of their several ancestors. See the names of the several breeds. See also Canidœ and Canis.
