Sorry, can't help you with any other members here.
We have one that comes to the local park, though -he's the park hussy...lol!! Such a gorgeous, big, boisterous boy. He just lumbers around and tries to hump everything that moves, it's hysterical. He's just a lovely dog. Well, a big gigantic puppy, really, the way he acts is very puppy-like, and I think he's only a year or two old. I believe they do have a long puppyhood, like GSDs.
