“No one could give a satisfactory answer to that question. The taming of the dog goes back to the earliest times and all remembrance of it is lost. There is the same deep obscurity as to its origin and the wild species from which it is descended. Nowhere has the dog been seen by travelers in its primitive state, in a state of complete independence. If some dogs are found leading a wild life, they are runaways; that is to say, dogs that have fled from domestic life to live as they please in desert regions. Such are those that burrow and hunt for themselves in the vast plains of South America. They are certainly descended from domestic dogs carried thither by Europeans; for at the time of its discovery, nearly four centuries ago, the New World had no dogs. All that can be affirmed is that the dog came to us from Asia already trained for man’s use. Apparently Asia made a gift to Europe of the oldest known domestic animals, such as the ox, the ass, and the hen.
“On account of the almost infinite variety in respect to its coat, its shape, and its size, it is suspected that the dog is not derived from a single source but comes from various species that have been improved [[184]]by man and profoundly modified in their characteristics by cross-breeding. Among these wild species to which is given the honor of being regarded as ancestors of the domestic dog, I will mention the jackal, which abounds in Africa as well as Asia.
Jackal
“The jackal looks a little like the wolf, but is smaller and is harmless to man. Its coat is red, varied with white under the stomach and black on the back. It has a pointed muzzle and erect ears. Its timidity causes it to feed on the remnants left over by animals bolder and stronger than itself. When the gorged lion abandons its half-devoured prey, the jackals, crouching in the neighborhood and waiting until his lordship has finished, hasten up in companies to the disdained carcass and clean it to the bone. For the same reason the jackal frequents in troops the outskirts of villages and encampments in the hope of finding garbage and carrion. In the daytime it stays quietly in its den among the rocks, but at nightfall it issues forth in quest of food with a sort of sharp howling that continues all night. There is nothing so disagreeable as the nocturnal concert of a band of jackals prowling around dwellings. One of them begins with a cry something like argee in a very piercing and prolonged tone. Scarcely has it finished when a second takes up the [[185]]refrain and improves upon it; then a third and a fourth, until the whole band has joined in, producing a veritable charivari composed of a mixed chorus of discordant howls. After this musical feat, solos are in order again, interspersed with choral productions; and so it goes on until daybreak. Such is the infernal music that awaits the sleeper every night.”
“Oh, what disagreeable neighbors!” exclaimed Jules. “If the dog had kept any of those detestable habits it would be a very troublesome animal, useful though it is.”
“The dog shows not seldom, it must be admitted, a mania for making the night hideous; but it cannot be reproached with anything comparable to the jackal’s concert. The dog has two cries, without counting those that are secondary. One of the two is natural, the howl; the other artificial, the bark. Is it necessary to point out to you the difference between the two?”
“I know what you mean, Uncle,” Jules was quick to reply. “The dog howls when it gives a long, wild cry, so mournful and terrifying in the night; it barks when it gives those short, jerky yelps. It howls from fright, sadness, ennui; it barks with joy and pleasure.”
“Yes, that is it. I told you, then, that howling is the dog’s natural voice. In it can be found, but with a very different action of the throat and a less sharp tone, something of the jackal’s cry. As for the bark, it is an artificial utterance; that is to say, [[186]]it has been acquired. Dogs that have gone back to the wild state, as for example those of South America, can no longer bark. Deserters from civilization, they have lost the language and are reduced to their primitive howling, which they share with the jackal and the wolf.”
“And how does a dog learn to bark when it is with us?”
