I'm not sure where you are coming from here casablanca. This situation is pretty clear. The type of dog doesn't matter- this could have been a cocker spanial, a pit bull, GSD, beagle, anything. A person puts their dog out into the yard on their own property, behind a gated fence. A 9 year old girl goes into the yard uninvited, then goes up to a large strange dog while it is eating and does who knows what to the dog- pets it, pokes it, hugs it, tries to feed it. The dog reacts. If the dog was truely aggressive it would have jumped her the minute she went into the yard.
To me, that blame is squarely on the kid and the kid's parents. The kid's parents are to blame because they should educate their child on a couple basic things- 1 you do NOT go into someone elses fenced in yard for ANY reason unless you are invited. 2 you do NOT go near ANY dog if the owner is not present. The only issue I can see the owner at fault on is the fact that he watched the girl approach the dog. If that was my yard and my dog, I would have been out the door yelling at the kid the second I saw her, not waiting for her to get near my dogs.
