German Shepherd Dog
Mouse is part of the K9-1 working dog program and is currently an active police K9. He has a great balance of being social with people and dogs (with caution around intact males), very good environmental nerves, strong hunt and prey drive, and very good natural aggression (fight drive). He is able to turn it off completely when out of drive.
He is trained in control, apprehension, man trailing, and specific scent detection.
