Topping out at nearly 28 inches  at the shoulder and often weighing more than 100 pounds, with a large  head, alert expression, and muscular frame, Cane Corsi are at a glance intimidating creatures. Bred as guard dogs for centuries, their imposing  appearance is their first line of defense against intruders. As one writer put it, “An understated air of cool competence, the kind of  demeanor you’d expect from a professional bodyguard, is the breed’s  trademark” and completes the picture of a dog not to be trifled with.
