Well I can't say enough good about this 2 yr old guy...he has the best temperament of any GSD I have seen. Quiet in the house, but playful outside. He loves to play ball and will throw it at you if you don't take it from him...he does need to learn not to jump, but knows his basic obedience. He gets along with the other dogs, is supposed to get along with cats, but when he went on a sleep over, he was very focused on the resident cats. He is a bit protective of his toy when playing, but listens very well when reprimanded to be nice. He seems to love everyone, but will stand between his person, when he feels a threat. A very discerning guy. He is housebroke and crate trained. He is a doll in the house. A very easy dog to have around.
