I'm with Goudy on this, if you fully understand and can comprehend what these dogs are capable of doing to you, if they see fit, you will not feel comfortable around them.
Why put your life in the hands of what a damn dog decides to do or not to do. Fucken stupid...
Unless, of cause, you don't mind having your face tore of the skull, muscles and tendons ripped from your bones etc, have at it..
