Based on the diversity of today’s pup breeds, scientists think that the dog was shaped by crossing many related species from the dog family. Included in this, Charles Darwin [36] and the ethologist of Austria, Konrad Lorenz, had been the initiators of the theory of evolution, who concluded that the ancestors of the domestic puppy were a wolf and a jackal [37]. Today’s established opinion, supported by the results of genetic analyzes, is that the domestic doggy developed from the small band of wolves, domesticated about 15,000 years ago.

It is not known exactly how the domesticated puppy was held. It is possible that dogs were the people who produced the initial step. Namely, if crazy dogs started to be small enough to be unsafe, to go to human they might collect waste materials, discarded bones and camps. Thus, people probably tolerated them because they were washing their surroundings. It is possible that they have begun to fascinate, approach them, and then domesticize them as safeguard dogs and companions. It had been only once agriculture has been progressing that the herds could be preserved. Or elsewhere: the canines followed a smarter line in the wish of getting anything from prey.

The initial remains of a domestic dog were uncovered in Mesolithic sites in different places. It seems that the earliest European breed was quite small and would usually be best in comparison to today’s small dog.

Many breeds result from a small number of animals, which leads to mating inside kinship. The result is several hereditary (genetic) illnesses common in some breeds, for example hip dysplasia (especially in German shepherds), epilepsy, ataxia, oculoskeletal dysplasia, and others
