It is true that no one can actually say for sure the origin of dogs, but it is believed that the history began about 40 million years ago in a remote sort of way.
Once upon a time, there was a small family of carnivores (animals that feed on meat) then called Miacidae. The Miacidae family had two descendants, Daphaenus - this gave rise to the bears.
The Cynodictis, a much smaller creature family, gave rise to the dog-like animal called
Tomarctus, which is believed to be the ancestor of dogs, wolves and jackals.

The origin of the domestic dog (Canis lupus familiaris) began with the domestication of the gray wolf (Canis lupus) several tens of thousands of years ago. Domesticated dogs provided early humans with a guard animal, a source of food, fur, and a beast of burden. The process continues to this day, as the intentional cross-breeding of dogs continues, to create the so called "designer dogs".
Archaeology has placed the earliest known domestication at potentially 30,000 BC, and with certainty at 7,000 BC. Other evidence suggests that dogs were first domesticated in East Asia.
Due to the difficulty in assessing the structural differences in bones, the identification of a domestic dog based on cultural evidence is of special value. Perhaps the earliest clear evidence for this domestication is the first dog found buried together with human from 12,000 years ago in Palestine.
As humans migrated around the planet, a variety of dog forms migrated with them. The agricultural revolution and subsequent urban revolution led to an increase in the dog population and a demand for specialization. These circumstances would provide the opportunity for selective breeding to create specialized types of working dogs and pets.
