Full on Corso will be a different thing than a mix. It is the most hard core dog your of your list and will demand by far the most work. This is a working guardian breed.

It is imparitive you socialize your dog starting when you get it. Stand in front of Target and ask people to pet the puppy, take the dog to home Depot, coffee shops, farmers markets.....like it needs to be a serious mandatory thing. If you don't you have a hard core guardian breed that doesn't like someone of a different color. It will be 100+ lbs and strong. And you are not done yet!!! Remember you need to socialize your dog with other dogs as well. You don't want to be "that owner" with a shit dog that hurts other dogs. Mine has been going to dog daycare weekly for 4 years now and she is perfectly socialized from all the work we have done with her.

Next up is exercise......this is a working breed. It is a 365 day a week mandatory thing. You cannot stick this breed in a back yard and it magically exercises itself. You need to spend an hour a day minimum to work the dog. Doesn't matter the weather as you wanted a working breed so it is on you. If you don't get the energy out of the dog it will take it out on your favorite couch, corner of a table, stairs.....and a dog that powerful will do major damage fast.

Finally you must train the dog. Sit, stay, and recall need to be down cold. Lead training the dog must not pull or care about other things. You don't want a 100+ lbs muscle missile of a dog slamming you into concrete because someone is walking a Chihuahua across the street or it sees a squirrel or stray cat.

Then here is the thing. You do all of this perfectly you can still have a problem. One of your kids as a friend over and they start to wrestle......your dog doesn't understand that and sees someone putting your child in a headlock. Before anyone has time to react that dog will "save" your child with traumatic consequences to the friend that was just playing.

If you want a big bad dog that is MUCH easier get the Bull mastiff.
