All of mind are like that with kids. My older femsle(non GSD) will walk away if they are bothering her to much, she is almost 10 so not as interested anymore. I don't allow the kids to do what the kids in this video are doing but I knows they can. In my house the kids don't seek out the dogs the dogs seek out the kids for interaction. I like it that way because it's not unwanted by the dogs. Mine also love sleeping with the kids, the dogs await patiently for the kids to wake up in the morning. Once the dogs know the kids are ready to go the dogs get excited and act like they haven't seen them in months.
