He looks like a great companion, and from what ive read im sure he will be loyal! I'm sure you did the full research, but for others (wikipedia)...
Powerful and imposing, a Cane Corso is highly suspicious of strangers and for this reason, aggression should never be encouraged. Because of their need to keep the status quo, Corsi often dislike new things, animals, and people, so the owner must be careful when bringing the dog around new places and people. Cane Corsi tend to be a quiet breed, though they will bark at anything they are unsure of, but for the most part, they like nothing better than staying next to their owner all the time.[3]
A true Corso should be indifferent when approached and should only react when a real threat is present. Of course, socialization is the key to controlling the dogs natural protective instincts, because a Corso will find anything threatening if not properly socialized as a puppy. If socialized properly as a puppy, a Cane Corso can get along with other dogs and people. Corsi are historically working dogs that need exercise and are at their best when they have a job to do.
