General History of Dogs
There is no incongruity in the idea that in the first period room very man in this world that became a friend and companion some sort of aboriginal representative of our modern dog, and that in exchange for their help to protect wild animals, and in monitoring their sheep and goats, he gave some of their food, a corner into his house, and came to trust her and care. Probably the animal was originally little more than an unusually gentle jackal, or a sick wolf driven by their peers in the wild marauding pack to seek shelter in an alien environment. One may well conceive the possibility of the association from the fact that some defenseless puppies are brought home by hunters and bred early to care for women and children. The dogs entered the house as toys for children grow to be considered, and should be considered as family members
In almost all parts of the world in the footsteps of a family of indigenous dogs are the only exemptions from the West Indies, Madagascar, the eastern islands of the Malay Archipelago, New Zealand and the Polynesian islands, where no signal any dog, wolf, fox or has existed as a true aboriginal animal. In the ancient Oriental lands, and in general among the early Mongolians, the dog is to be wild and forgotten for centuries, prowling in packs, gaunt and like a wolf, and who walks the streets today and in the walls of every city in the East. There was no attempt to appeal that in human companionship or to improve the workability. It is not until we examine the records of the higher civilizations of Assyria and Egypt, to verify the existence of different varieties of canine form.
The dog was not greatly appreciated in Palestine, and in both the Old and New Testament that is commonly spoken of with scorn and contempt as a "filthy beast." Even the familiar reference to the Pastor in the Book of Job "But now they are younger than I joke, whose parents had neglected me to establish with the dogs of my flock "is not without a suggestion of contempt, and it is significant that the only biblical allusion to the dog as a companion of man recognition occurs in the apocryphal Book of Tobit (v. 16), "So they went forth both, and the young dog with them."
The large crowd of different breeds of dogs and the great differences in size, points, and general appearance are facts which make it hard to believe he might have had a common ancestor. One thinks of the difference between the Mastiff and the Japanese Spaniel, Deerhound and the fashionable Pomeranian, the St. Bernard and the Miniature Black and Tan Terrier, and is perplexed in contemplating the possibility that the descent from a common ancestor. However, the disparity is greater than that between the Shire horse and Shetland pony, Shorthorn and the Kerry cattle, or in Patagonia and the Pygmies and all dog breeders know how easy it is to produce a variety in the type and size by studied selection.
To properly understand this question, we must first examine the identity of structure in the wolf and the dog. This identity of structure may best be studied in a comparison of the skeletal system, or skeletons of the two animals, which so closely resemble each other that their inclusion would not be easily detected.
The vertebral column consists dog of seven vertebrae in the neck, thirteen in the back, seven in the loins, three sacral vertebrae and twenty-twenty-two in the queue. In the dog and the wolf are thirteen pairs of ribs, nine true and four false. Each has forty-two teeth. Both have five front toes and four back, while outwardly the common wolf has both the appearance of a large bare bones of dog, a popular description of a serve to the other.
Nor are their habits different. natural voice howl of the wolf is a very strong, but when confined with dogs will learn to bark. Although it is a carnivore, which also feeds on plants, and when sick going to bite the grass. In the chase, a pack of wolves will divide into parts, one following the trail of the quarry, the other trying to intercept their retreat, exercising a considerable amount of strategy, a trait that is exhibited by many of our sporting dogs and terriers when hunting in teams.
Another important point of similarity between the Canis lupus and the Canis familiaris lies in the fact that the period of gestation in both species is sixty-three days. There are three to nine cubs in the litter a wolf, and these are blind twenty days. They are suckled for two months, but after that time are able to eat half-digested flesh disgorged for them by his mother or his master.
The dogs native to all regions approximate closely in size, color, shape and habit to the native wolf of those regions. In this most important circumstance there are too many times to allow it was seen as a mere coincidence. Sir John Richardson, writing in 1829, observed that "the similarity between North America and the wolves domestic dog of the Indians is so great that the size and strength of the wolf seems to be the only difference.
It has been suggested that an undeniable argument against the lupine relationship of the dog is the fact that all domestic dogs bark, while all wild Canidae express their feelings only by howls. But the difficulty here is not as great as it seems, because we know that jackals, wild dogs, and wolf pups reared by bitches easy to acquire the habit. On the other hand, domestic dogs can run wild forget how to bark, while there are some who still have not learned to expression.
The presence or absence of the habit of barking can not, then, be regarded as an argument to decide the question of the origin of the dog. This stumbling block consequently disappears, leaving us in the position of agreeing with Darwin, whose final hypothesis was that "it is likely that domestic dogs the world have descended from two good species of wolf (C. lupus and C. latrans), and two or three other doubtful species of wolves namely, the European Community, India, and forms the northern Africa; of at least one or two canine species in South America, from different races or species of jackal, and perhaps one or more extinct species ", and that blood of these, in some cases, mixed, runs through the veins of our domestic breeds.
