I have a Ridgeback/Mastiff cross. This seems to be a real good cross for a farm dog. The Pitbull/Rotweiler crosses are great pig dogs(I've had 3), but not real good around kids. I have had Dobes, Labs, Bouviers des Flanders ( REAL good dog but unless you are in acold climate, they are prone to coat problems) and Saint Bernards for big breeds and been around alot of others extensively. The Ridgeback/Mastiff cross (dad a ridgeback) seems to be a VERY good family California farm dog. He will bite your ankle(a little) if you are a stranger and don't back off from his barks, I'm SURE he would go farther on a sneaky no good. When his hair stand on end his 125 pound snarls are a thing to behold
