Based on the diversity of today’s dog breeds, scientists think that the dog was created by crossing several related species from the dog family. Among them, Charles Darwin [36] and the ethologist of Austria, Konrad Lorenz, were the initiators of the theory of evolution, who figured the ancestors of the domestic dog had been a wolf and a jackal. Today’s established opinion, backed by the full total results of genetic analyzes, will be that the domestic canine developed from a small group of wolves, domesticated about 15,000 years back.

It isn’t known just how the domesticated pet was held. It’s possible that dogs were the people who made the initial step. Namely, if crazy dogs started to be little enough to end up being unsafe, to go to human discarded bones, they might collect waste materials and camps. Thus, people tolerated them because they were cleansing their surroundings probably. It’s possible that they have started to fascinate, approach them, and domesticize them as safeguard dogs and companions then. It was only once agriculture has been progressing that the herds could be preserved. Or elsewhere: the dogs implemented a smarter collection in the hope of getting anything from prey.

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

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