Where did the doggy land from?

Dogs are believed to be the descendants of wolves, which had a much wider distribution than today. The skeletal structure of smaller wolves and that of a dog matches to a high degree.
Wolves move in packs and choose a leader among themselves. They were used by mankind for hunting and safe-guarding their property.
Breeding between wolves from different parts of the world led to a new kind of a species which are now seen as "dogs." Some also suggest that, dog could have descended from the golden jackal.
