I like also Cane Corso although I haven't owned any dog ever but I think my first one will be a Samoyed. However, from what I read Cane Corso not only that it is a good guarding dog but it's also a good baby sitter if I may say. I have seen some videos about it and it's not all just muscles. One of my favorite breeds.
My Mastiff loves my grandson and just sits with him.What I like is he is very gentle with children. He gets concerned when he cries and is very protective. No one who he doesn't know will be allowed near my grand son.
My babies wish you a happy New Year :)
