Mine bark very seldomly. It's to the point that when they do bark it sometimes startles me because it generally isn't without reason. Although GSDs are sometimes known to "talk" a lot. Kavik, my GSD - Husky mix is my little chatty kathy, she is also my tantrum throwing dog. Haha I'm sure most of that comes from the Husky side of her. Nikkia, my full GSD, is more of the silent type. Doesn't talk much, doesn't whine much (unless she thinks we're on our way to the beach! Haha) and rarely barks.
