Early, frequent socialization is essential. Purchase a Cane Corso puppy from a breeder who raises the pups in the home and ensures that they are exposed to many household sights and sounds. Continue socializing your Cane Corso throughout his life by taking him to puppy kindergarten class, introducing him to friends and neighbors, and planning outings to local shops and businesses. This is the only way he can learn to be discriminating between what is normal and what is truly a threat.
However, even with the right amount of socialization Cani Corsi may not fully warm up to people other than his family. The Cane Corso is first and foremost a guard dog, and he takes his responsibilities seriously.
