Based on the diversity of today’s pet breeds, scientists believe that the dog was created by crossing various 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 idea of evolution, who figured the ancestors of the domestic dog were a wolf and a jackal [37]. Today’s founded opinion, backed by the total results of genetic analyzes, can be that the domestic dog developed from the small band of wolves, domesticated about 15,000 years ago.

It is not known just how the domesticated puppy was held. It’s possible that dogs were the ones who produced the initial step. Namely, if crazy dogs started to be small enough to become unsafe, to visit human discarded bones, camps plus they could gather waste. Thus, people tolerated them since they were cleaning their surroundings probably. It is possible they have begun to fascinate, approach them, and domesticize them as safeguard dogs and companions then. It had been only when agriculture has been progressing that the herds could possibly be preserved. Or elsewhere: the dogs followed a smarter range in the hope of getting anything from prey.

The initial remains of a domestic dog were found out in Mesolithic sites in various places. It seems that the initial European breed of dog was quite little and would usually be best compared to today’s small canine.

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