Psuedo swearing is frowned upon on this board, just a heads up.
As far as how 'bad' you want the dog to be when speaking with breeders you may want to clarify to what level you want the dog to respond to threats (i.e. bark to alert or bite if someone tries to attack you/your family).
Sorry I don't know any breeders in your part of the country to help more specifically. Good luck with your search!
