A fearless protector so especially with a CC to not do this training puts the dog in a fearful situation and be doing you and the dog a disservice, these dogs were not bred to get kissed and go slowly with training. Get the empty bottles and bin ready, start the lawn mower daily, my lawn mower guy actually knew that I needed to do that and ran it close to us everytime he mowed the area 2 times weekly, the states has construction everywhere now, good idea to walk her near construction sites, especially loud ones, car washes helped tremdously and basically any loud obnoxious noises that would normally scare her. This is an important part of training don't take it lightly.
The Cane Corso description:
The Cane Corso Italiano is great with children in the family. Docile and affectionate with the owner, they are protective yet gentle. The Cane Corso has a very stable temperament. It makes an excellent guard dog and watchdog. It will not wander from the home. They stick close to their masters. If necessary he becomes a terribly brave protector of people, house and property. The Cane Corso is not a fighting dog. They were bred as powerful working dogs for hundreds of years. Therefore they will not go out "looking" for a fight, but on the other hand they will not back down from other dogs who try to dominate them. The Cane Corso requires an experienced owner who knows how to display a natural authority over the dog. It can be aggressive with strangers and other dogs if not socialiized or if it sees itself above humans in the pecking order. It should be carefully socialized when it is a pup. It is highly recommended that these dogs become fully obeidience trained. If a Cane Corso is fully trained with an owner who is firm, confident and consistent, setting rules the dog must follow and placing clear limits to what he can and cannot do, along with providing the proper daily mental and physical work, the Cane Corso will be an amenable companion. Learn what makes the Cane Corso tick and treat his breed accordingly. Suspicious of strangers, but wonderful with the family, a well-balanced Corso will put up with strangers if the owners are present. When raised correctly, the dog should be submissive to all members of the family. Corso ears were originally cropped to help them ward off wolves while protecting livestock. Their ears are much more sensitive than the rest of their bodies. Generally, they're practically impervious to pain otherwise, so many Corso owners are often disappointed to find that electric "invisible fence" containment systems don't deter their dogs.
