Why Dogs Are the Most Useful Animal to Humans

Why Dogs are the Most Useful Animal to Humans For as long as anyone can remember dogs have been bred and used to help humans. Whether it be for hunting and gathering, companionship, to help with the disabled, or to help law enforcement officers do their jobs better, dogs are the most versatile and useful animals to humans. Most scientists agree that dogs are descended from the Grey Wolf. Dr. Robert K. Wayne of UCLA has shown through DNA research that the Grey Wolf and common dog are so closely related that they can interbreed and produce fully viable offspring (Dog names, 2004). It is thought that a human hunting party came across a very young wolf cub and decided to take it with the members of the hunting group, and that was the beginning of the domestic dog. Wolf and man had a few important things in common as they were both hunters and hunted in packs. Remains of dogs have been found dating back 10 to 15 thousand years (Dog names, 2004). There are hundreds of breeds that have been developed by man throughout history. These different breeds were developed due to the changing requirements of man through history. (Dog names, 2004)
Breeds of Dog
There are many different categories of dogs that have been developed through history, and they all had and have a specific purpose for the people who bred them at the time and continue to breed them today. Some different categories of dogs that were bred are sight hounds, scent hounds, working dogs, sporting dogs, terrier dogs, non-sporting breeds, and toy breeds (Dog names, 2004) Breeds in the sight hound group include the Afghan Hound, Basenji, Irish Wolfhound, and the Greyhound. Sight hounds are called sight hounds essentially because they have excellent vision. They also have a long jaw and neck, which help them with catching their prey (Sight Hounds, 2004). Looking closer at the greyhound they have been bred for thousands of years to hunt and outrun their prey (History and evolution of dogs, n.d.) Another group of
