This ancient breed was primarily used as a guard dog. The Mastiff was favored by nobility as a hunting companion and revered by peasants as a family and livestock protector. They were also used as arena gladiators where they participated in bull, bear, and dog combat. The Mastiff was nearly extinct by the end of WWII, but was saved with imports from the United States and Canada.
