Based on the diversity of today’s dog breeds, scientists believe that your dog was formed by crossing many related species from the dog family. Included in this, Charles Darwin  and the ethologist of Austria, Konrad Lorenz, had been the initiators of the idea of evolution, who figured the ancestors of the domestic puppy had been a wolf and a jackal . Today’s established opinion, supported by the outcomes of genetic analyzes, is certainly that the domestic canine developed from the small band of wolves, domesticated about 15,000 years back.
It is not known exactly how the domesticated dog was held. It’s possible that canines were the ones who produced the first step. Namely, if wild dogs started to be small enough to become unsafe, to visit human camps, they could collect waste materials and discarded bones. Thus, people possibly tolerated them because they were cleaning their surroundings. It is possible that they have begun to fascinate, approach them, and then domesticize them as safeguard canines and companions. It had been only when agriculture was progressing that the herds could be preserved. Or otherwise: the dogs followed a smarter line in the wish to getting anything from prey.
The first remains of a domestic canine were uncovered in Mesolithic sites in various places. It seems that the earliest European breed was quite little and would usually be best in comparison to today’s small doggy.
Many breeds result from a small number of animals, that leads to mating in kinship. The effect is several hereditary (genetic) illnesses common in a few breeds, for instance hip dysplasia (especially in German shepherds), epilepsy, ataxia, oculoskeletal dysplasia, among others
