Based on the diversity associated with today’s pet breeds, scientists believe that the dog was formed by crossing various associated species from the dog family. Among them, Charles Darwin  and the ethologist of Austria, Konrad Lorenz, had been the initiators of the theory of evolution, who figured the ancestors of the domestic pet were a wolf and a jackal. Today’s established opinion, backed by the total results of genetic analyzes, is definitely that the domestic pet developed from a small group 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 first step. Namely, if crazy dogs started to be small enough to end up being unsafe, to go to human they might collect waste materials, discarded bones and camps. Thus, people possibly tolerated them since they were cleaning their surroundings. It’s possible they have begun to fascinate, approach them, and domesticize them as guard dogs and companions then. It had been only once agriculture had been progressing that the herds could possibly be preserved. Or otherwise: the canines followed a smarter range in the wish to getting anything from prey.
The initial remains of a domestic dog were uncovered in Mesolithic sites in different places. It seems that the initial European breed of dog 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 in kinship. The effect is various hereditary (genetic) diseases common in a few breeds, for instance hip dysplasia (especially in German shepherds), epilepsy, ataxia, oculoskeletal dysplasia, and others
