i hear a lot of stories regarding the true origin of the cane corso. I know the derrived from the canis pugnax. But im talking about the origin after it was recovered from near extinction so my main question is what breeds were added to create the modern day cane corso? i know somewhere in there is some Neapolitan but i also read somewhere that the the american pitbull terrier was added in the mix, i also spoke to a person from the uk who breeds them and he told me about something called a root cane corso that were mainly bred by italians in the 70s that had bullterrier in them but they are extremely rare and that most cane corsos are mostly mastiff type and not bullterrier.
