In line with the diversity associated with today’s pup breeds, scientists think that the dog was produced by crossing many associated species from the dog family. Among them, Charles Darwin  and the ethologist of Austria, Konrad Lorenz, were the initiators of the idea of evolution, who concluded that the ancestors of the domestic pet were a wolf and a jackal. Today’s established opinion, supported by the outcomes of genetic analyzes, is usually that the domestic pet developed from the 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 canines were the people who produced the initial step. Namely, if wild dogs started to be small enough to end up being unsafe, to visit human camps, discarded bones and they could collect waste. Thus, people probably tolerated them since they were cleaning their surroundings. It is possible they have begun to fascinate, approach them, and then domesticize them as guard dogs and companions. It was only once agriculture had been progressing that the herds could be preserved. Or otherwise: the dogs implemented a smarter collection in the wish of getting anything from prey.
The first remains of a domestic puppy were discovered in Mesolithic sites in various places. It seems that the earliest European breed was quite little and would generally be best compared to today’s small doggy.
Many breeds result from a small number of animals, which leads to mating in kinship. The effect is numerous hereditary (genetic) diseases common in a few breeds, for instance hip dysplasia (specifically in German shepherds), epilepsy, ataxia, oculoskeletal dysplasia, and others
