I tried for a while to learn about the makeup of the Corso, but it's too unclear to me. So, I have decided to simply find a breeder who produces dogs I like the look of, and hopefully does health testing, and the breeder will communicate with me, and doesn't engage in the silly overpricing you see today. I'm not going to be too concerned if the dog has Boxer, or Dane, in it. As long as it has a solid temperament – stable, good courage and defense drive, and biddability. But that's just me. I know I haven't done much to answer your question.
