ultimate security prevention system

Surely a mistake?

I knew a guy who had a Bullmastiff. It was a sweet dog, but ultimately too strong. It pulled me and another friend of mine through a snowy forest when we were taking it for a walk. It was also terrified of a small toy dog that said "hau hau hau hau..." as we learned when Jussi introduced us to his dog. :)

I've never met a Cane Corso but I've heard they can be challenging as they have a dominating will as a breed trait.
