You'd be surprised. My Balto looks like a fluffy muppet. He will slurp on anybody that pets him and he breaks up fights at the dog park. But when I took him to be temperament tested, I thought he was going to kill the tester that came after him with a stick. Of course, that's what the Laekenois was breed for, to be a guardian and a general working dog. Much like the GSD.
