the Cane Corso breed is not one to fuck around with. It was bread to fight gladiators in ancient Rome. I have a friend that trains dogs for CPD and he says these things are a hazard to anyone outside the family that it was socialized with. But all in all, pound for pound the best guard dog, period. (im getting one in June, the thing is going to be coming from a 120lb dad and a 153lb mom...its gonna be a big mother fucker)
