Mary you should contact the italien special club for the breed. here is the link - http://www.canecorsoitaliano.it/ regarding DNA test. it is not possible to make an DNA test and say this dog is a mix of these and these breeds. you can only make the test and say, this dog is after this female and that male, or not... nothing further is possible with DNA. so the person who wrote about that in a different forum, was a good storieteller 8-)
