I grew up with Tibetan Mastiffs (still have 3 with my parents back home), so I have no problem with large dogs. I have two Dogo Argentino pups at home, and I want to purchase one more pup other than Dogo. I am thinking of Neomastiff / Cane Corso/ Fila, I like them all, but my situation only allow one of them. What do you think? Which one should I get? Thank you for your suggestion.
