I wasn't speaking about kids, more about adults. From what I've seen with my GSD, he accepts all kids. I have 9 nieces and nephews, who he might see 1-2 times a year, not like he's around them all the time, and he freely accepts them and lets them hang all over him the way kids do. They are not a quiet bunch of kids either! I have seen him "herding" them too. He's also very accepting to kids we see when we go to the park, on walks, and other public places. Adults are ok as long as I "approve" of them. Strangers can come into my house as long as I let them in. I'm not sure what would happen if a friend who he didn't know just walked in unannounced. Of course the early warning system of Bruzer and Daisy would at least alert me that someone had come in. We have some friends who when they come down might let themselves into the back yard if they know we are doing a BBQ, but if we're inside, they are alone out there, and I've commented to them that it might not be a good idea. Better safe than sorry.
