I find that German shepherds need a lot of obedience training and socialization

I think you can lump in any large breed that tends to be dominant, like rotties, pits, American Bulldogs, etc. They need to be put in their place and trained right, or they are a bad accident waiting to happen.

though, I know a guy who has a German shepherd — very well trained and the guy takes a real interest in his dog. He told me he once had a rottwieler who was devoted to his wife and daughter but would attack HIM!
