Dogs have been domesticated for most of human history and have been a delight to many over the years. Stories have been told about brave dogs that served admirably in wars or that risked their lives to save persons in danger. When the Roman city of Pompeii was destroyed by Mount Vesuvius in AD 79, following the evacuation, searchers found evidence of a dog lying across a child, apparently trying to protect the youngster. Since dogs have been with humans since prehistoric times, over the years they have been invaluable friends and provided invaluable services to man. Dogs have pulled sleds through the Arctic, delivered messages, herded cattle and sheep and recued people that have been trapped or lost.
The dog is part of a family of similar animals that include wolves, coyotes, foxes, jackals and wild hunting dogs such as the Dingo and African Wild Hunting Dog, who all share common characteristics. Many of these wild dogs have been claimed to be the domsetic dog’s wild ancestor but the exact origins of the dog are uncertain. Some believe that the ‘Miacis’, a weasel-like animal, is the ancestor of the ‘canids’ as well as other families such as bears, racoons, civets, hyenas and cats. From ‘Miacis’ evolved ‘Cynodictis’, a dog-like animal from which later evolved the dog family.
A breed of dog called the ‘Saluki’ appears on the ancient tombs of Egypt from around 2100 BC and is thought to be the dog mentioned in the Bible. Its body has often been found mummified along with the Egyptian Pharaohs in Pyramids. The ancient Greeks and Romans developed a number of breeds including the greyhound, mastiff and bloodhound. The Romans made sacrifices to the dog-like god Procyon.
