The Cane Corso is an Italian breed of dog used mainly as a guard dog. It is of the large molosser type.(Wikipedia)
The Cane Corso is a large, lean molosser-type dog. It is well muscled and looks more athletic than most other mastiffs, tending less toward sheer bulk like the English Mastiff and more towards definition like the original (Wikipedia)
Cane Corsos are considered to have an even, stable temperament. They are easy to train, generally good with children, and calm with their primary guardians.(Wikipedia)
