In line with the diversity of today’s pet dog breeds, scientists think that the dog was shaped by crossing many associated species from the dog family. Among them, Charles Darwin [36] and the ethologist of Austria, Konrad Lorenz, were the initiators of the idea of evolution, who concluded that the ancestors of the domestic doggy had been a wolf and a jackal [37]. Today’s founded opinion, backed by the full total results of genetic analyzes, will be 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 dog was held. It is possible that canines were the people who produced the initial step. Namely, if crazy dogs began to be little enough to become unsafe, to visit human they could collect waste materials, discarded bones and camps. Thus, people tolerated them because they were cleansing their surroundings probably. It is possible that they have begun to fascinate, approach them, and then domesticize them as guard dogs and companions. It was only when agriculture had been progressing that the herds could be preserved. Or elsewhere: the canines implemented a smarter collection in the hope of getting anything from prey.

The first remains of a domestic canine were found out in Mesolithic sites in different places. It appears that the earliest European breed was quite little and would usually be best compared to today’s small doggie.

Many breeds result from a small amount of animals, that leads to mating inside kinship. The result is various hereditary (genetic) illnesses common in some breeds, for example hip dysplasia (specifically in German shepherds), epilepsy, ataxia, oculoskeletal dysplasia, among others
