comparing the rottweiler with a corso, is like comparing the sun and the moon. there is a world of difference between those 2 breeds. the rottweiler is so dominant and will allways test you, and fight you for the leadership. he needs a firm or hard hand, when you train him. he is allso very dog aggressive. rottweilers scare the hell out off me. for some reasson they allways bite me 8O the cane corso is an angel, so easy to train, he will never take any fights with you, he is totally submissive and is great with all other dogs and animals, when socialised correct. he must be trained with your mind and with love. you wont find a braver, tuffer or more loyal dog than the cane corso. only a bullit can stop him, if he thinks that his owner is in danger (but the owner can stop him, just by changing the expression in his face).he is the juwel among dogbreeds (if you are the right type of owner). it is an ultra intelligent breed, and he reads people like an open book, in a split second. So he needs an owner who is likewise :D I control my pack only by bodylanguige and different faces. its very seldom I need to use the voice, mostly with puppys and the teenagers im not sure if you can compare the CC with the neomastiff. My experience with the neomastiff is, that he is ultra dominant to people, even the owner. But maby its just bad breeding we have in denmark, i dont know. just my oppinion :D
