For as far back as the Stone Age, dogs have been devoted friends to humans, and it's not just because they are so adorable.
Dogs have been around since the beginning of time.
They are intelligent in a manner that is excellent for humans, a state of affairs that was fully purposeful;
over the course of millennia, people have developed dogs to be the ideal canine companions.
At any point in time throughout history, the most intelligent dog breeds have served as more than just man's best friend.
They have been navigators and field guides, wartime comrades, detectives, garbage collectors, movie stars,
and instructions that are communicated by its human, as well as the dog's ability to express itself through barks, body movements, and actions.
