The Cane Corso is an Italian mastiff that once guarded farms, drove cattle and helped hunt wild boar in southern Italy. The breed nearly disappeared by the 1970s and was rebuilt from a few survivors in Puglia. Adults are large to giant, usually 85 to 120 pounds, with a broad head, a short, stiff coat in black, gray, fawn or red, often brindled, and a muscular frame.
Many Corsos are devoted and calm with their family but watchful with strangers, and some dislike other dogs. That guardian streak calls for early socialization, reward-based training and confident handling. In Cincinnati, that means planning leashed walks past neighbors and choosing off-leash areas carefully. Many dogs labeled Corsos are mixes, so size and temperament can differ from dog to dog.
