The Cane Corso is an intimidating breed at first glance, with a muscular body and large head. Corsos come from Italy, where they were employed largely as guard and hunting dogs because of their power, courage and willingness to work. A very intelligent breed, these dogs are easily trained and versatile, and at the same time are intensely loyal to their humans. Corsos are great with children, make excellent family pets and tend to be protective of their families. Despite the Cane Corso's size and strength, Corsos have a medium energy level.
