Corso is very smart. Combine that with his overbearing personality, and you can easily see how he could dominate a family without solid leadership and boundaries. He will test you to see how far he can go. It is important to let him know from the beginning what the rules are and to make sure all family members also understand the rules. Adopt a “nothing in life is free” policy, requiring him to perform a command such as “sit down” or “lie down” before rewarding him with food, treats, or toys.
