From the past ccientists have a discussed about the history of Dogs. In todays time we can see dogs different breeds, shape and size. This is believed to be a effect of a vital point in evolution is happened thousand years ago in past - The Taming of the Grey Wolf. Great Scientists believe that every dog breed is a successor of the "Canis Lupus" - the "Grey Wolf".
In history humans and wolves were both hunters, they would have known of each others existance. Humans took the wolf cubs because the mature wolf are harmfuland cubs can be adapt according to human conditions. As the wolf cub grow, they would be less fearful of humans and therefore be semi-tamed. A semi-tamed wolf is more valueable for the human beings, they would have benefited like, wolfs hunting style and power to sense, one thing more they can even give them warning in danger.
As the course of taming wolves was done by humans in this time period. Human choose only those breeds which are friendly and they discard aggressive breeds of wolfs. Every human trait the wolf according to their own need like size, hunting, coat length and retrieving ability of different animals, and guarding ability would have been some traits involved with the selective breeding process.
In this time period human started dog trading also, with this dog breeding also began. Today all regonized dog breeds are placed in one of seven dog breed groups:
