so how does one know that a dog is truly protective and would defend against an attacker? They could look all protective, but when push comes to shove, they could back down. Do Cane Corso's have temperament tests like what they do with Filas? I'm just wondering, because all my dogs (2 Tosas and 1 EB) show protective behaviour, but I have no idea if they would really stand up to an intruder or attacker.
