As a family dog, guardian, company, attack dog, fighting dog etc etc.

They are very beautifull, massively built, strong and slober like crazy. This is the breed of dog used in the movie Turner and Hooch. They are very affectionate and are actually good with kids. They need a lot of room and excercise. As far as fighting, I am not going to even comment on it, since I don't agree with it and it is highly illegal.
