I have known at least 4 families with this breed of dog and every one was a big baby!
Just like with what they call a pit bull, it is all about how they are raised from a pup that determines what the dogs temperament will be!
Same goes for any breed dog for that matter!
My daughter-in-law is a Vet Tech and they have 2 they got from Pittie Rescue, one was severely mistreated and had been burned on her back and head. It took a while for her to trust people but she took to their kids immediately and is the most loving dog you will find!
