The Cane Corso is an Italian mastiff that worked southern Italian farms, guarding property, driving cattle and helping hunt wild boar. The breed nearly vanished 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, rectangular frame.
Many Corsos are loyal and affectionate with their families but serious and watchful toward strangers, and some don't get along with other dogs. That means early socialization, steady reward-based training and confident handling, especially in a city where dogs must stay leashed in public. Many shelter dogs labeled Corsos are mixes, so size and temperament vary from dog to dog.
