[quote=tosamama]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.[/quote] IMHO, Any good solid dog will defend his home. I have rescued and owned a lot of large breed dogs in last 30 years and I can say I never had any that did not try to protect what was his...Remember dogs like people come in all different mindsets ,some might not test worth a crap but when push comes to shove I want my dog with me.They won't ALL be great at it but damn it they WILL give u enough time to cock and load and dial 911..
