Everyone is giving good advice here, especially amkuska.
Secuono, who occasionally comes online here, seems to be very excellent with dogs. She, and some others I can't remember who, have a breed of dog that seems perfect for small farm/garden places.
Shoot* I can't remember the name of the breed, but it is something synonymous with "really good protective, even maternally protective, friendly to friends, frightening to bad things, really great breed of dog". I'm sure that's close! To the uninformed like me, they look kind of Samoyed or Pyranee.
She's put up photos of them mothering lambies and watching the chickens.
Marshall it sounds like you are thinking of Maremmas A TG member peteyfoozer owns 2 and has an interesting blog (Range to Range) of life on the ranch with those wonderful dogs.
