DNA testing and fossil examinations show that dogs originated possibly as far as 150,000 years ago. Paintings of the Pharaoh Hound date way back to 3000-4000 B.C. Dogs were around in Bible days because they are mention in bible passages. There is evidence that thousands of years ago man had already selected different breeds distinguished by their size and morphology, making it clear that man has been raising different kinds of dogs according to what he needed for hunting, shepherding, herding, defending, guarding, sledding, pulling, or just to play with his children. The genetic structure of the dog has been manipulated for thousands of years by man, man searching for the perfect dog that matches certain needs. Breeders work to improve health, physical structure, quality, temperaments and intelligence. Lately it seems that the only people who care about the future of the purebred dogs are the breeders who raise them. We have somehow revolutionized into a generation where many feel we no longer have a need for dogs, therefore the purebred dog is in great danger of extinction. Realistically it has taken thousands of years to create our 300+ breeds so the thought that it will only take 10-15 years to undo all of this work is astonishing.
