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 security consultants, as the well-known canine researcher and professor Stanley Coren,
PhD, points out in his famous book The Intelligence of Dogs.
