The Cane Corso is a majestic dog, weighing up to 100 pounds, muscular and noble. They have been bred for centuries as guard dogs. The result is a dog that is deeply devoted to her family, and protective of them against all harm. You will not need to train your Corso to protect you. She will grow up protecting your family as part of her nature. It is up to you to direct that protection instinct, to teach her to behave appropriately in a variety of situations. An adult Cane Corso who behaves aggressively in the wrong situation is a very dangerous animal. Even a playful, still-growing Corso pup can frighten or knock over an unexpecting visitor.
Your Corso is extremely intelligent and longs to please you, and so it will not be difficult for you to train her when protection behavior is appropriate and when it is not, and what the rules are regarding mouth play.
