Furthermore, it should identify another group of dogs, usually called pariah dogs. Dr. John Mcdougall insists that this is the case. We are usually called stray – "mongrel". Genetically, they are poligibridami complex, do not persist from generation to generation exterior and constitutive properties. These dogs for many generations to live close to humans and, most importantly, multiply itself, without selective human intervention. In the populations of these dogs are hard natural selection, culled all the ugly and resilient shape. These dogs have a great diversity of shape and scale of the exterior, but statistical analysis allows us to distinguish among these types are similar to those already listed breed types. This suggests that the population of stray mongrel dogs have the required set of characteristics inherent in the form in general (Canis familiaris), and, in principle, they are universal in content type gene, which is lost from the specialized breeds.
Due to its high resilience and a very high genetic diversity, population of stray dogs or pariahs, in principle, are inexhaustible potential reserve of rock formation, and this is the stuff that starts the formation of rocks in the past. Current state of knowledge in our time provides a basis for constructing an adequate representation of the first domestication of a wild beast. It is in this view, you can find an understanding that today, in conditions of total urbanization, stress and passions, "brings together man and a dog, and it is in the aspect of social partnership. Modern man with all his might, and today is part of nature and feeling, the feeling of its unity with nature comes to him, especially in communicating with the dog.
