We get him out to socialize a bunch, he is very territorial, but he will get tired out in the yard and sun on the lawn or the porch, but its' usually when I initially let him out that he will be on the prowl or sit and watch. He's been to obedience and socialization classes when he was 7 months old. An extremely smart dog, as I'm sure most of everyone's GSD's are. His intelligence never ceases to amaze me. He's extremely easy to train, but I apparently am failing in giving him things to mentally exhaust him. Thanks for the great info on neuturing him. I am somewhat relieved to learn that at least some of you have experienced something similar, albeit not to this extreme.
