With the right trainer and family, these dogs are exceedingly loyal, and they are great guard dogs. They may not make as good with watchdog duties as neither they nor they parental purebreds are prone to barking. Because these dogs are mixed, how much of which parent breed you get will not be obvious until they are mature.
American Pit Corsos are intelligent enough, and they will be a bit headstrong. They must be made to firmly understand that they are not the leader of the pack, however, or you will have problems. These dogs understand how smart and strong they are, and they will use both traits to try and get what they want.
They are great guardians for your family, provided they respect you. Once they do, your Pit Corso will be loyal to the very end. They won't hesitate to put themselves between you and a threat. They are also very playful and are at their best when they are made to feel comfortable and not threatened.
As the American Pit Corso comes from two dog breeds that have long been historically trained to hunt big and dangerous game, you can be sure you will have a very strong dog. It's more than merely tiring them out that you will want to exercise them for a couple or more hours daily; it's to prevent anxiety as well as help socialize them.
