The Cane Corso is an Italian mastiff that worked southern Italian farms, guarding property, driving cattle and helping hunt boar. The breed nearly disappeared before it was rebuilt from a few survivors in Puglia, starting around the 1970s. Adults are muscular, rectangular dogs, large to giant, usually 85 to 120 pounds, with a short, stiff coat in black, gray, fawn or red, often brindled.
Many Corsos are devoted and calm at home but serious guardians with strangers, and some don't tolerate other dogs. That drive calls for early socialization, steady reward-based training and a secure yard. The short coat makes grooming easy, so the real work is exercise and training. Dogs vary, and plenty of shelter dogs labeled Corsos are mixes, so judge the dog in front of you.
