The Corso is one of many Mastiff-type dogs. This one was developed in Italy and is said to descend from Roman war dogs. He is more lightly built than his cousin, the Neapolitan Mastiff, and was bred to hunt game, guard property, and be an all-around farm hand. Their work included rounding up pigs or cattle and helping to drive them to market.
The word “cane,” of course, is Latin for dog and derives from the word “canis.” The word “corso” may come from “cohors,” meaning bodyguard, or from “corsus,” an old Italian word meaning sturdy or robust.
The breed declined as farming became more mechanized and came near to extinction, but starting in the 1970s dog fanciers worked to rebuild the Corso. The Society Amatori Cane Corso was formed in 1983, and the Federation Cynologique Internationale recognized the breed in 1996.
A man named Michael Sottile imported the first litter of Corsos to the United States in 1988, followed by a second litter in 1989. The International Cane Corso Association was formed in 1993. Eventually, the breed club sought recognition from the American Kennel Club, which was granted in 2010. The breed is now governed by the Cane Corso Association of America.
