> s the dog actually staring at the girl before she comes into view on the camera?
I couldn't see the dog to start with, but when his head popped out in the isle, it was clear he was trying to get the little girl. From that point on, it looks, to me, as if he does not stop staring at the little girl, he was ready before she got close enough to grab.
However, watching it over a couple of times, the first time the dog pops out coincides with the bloke getting of his chair and the chair being pushed out - that is the instant the dog steps forward, the man then taps his pocket, the dog looks at the man and retreats (man is not aware of this, the fantastic bloke is not paying any attenetion to his dog

).
The man could have stopped this from happening if he was watching his dog.
It was not an unpredicatable attack, the dog gave clear signals as to what he was going to do - the reason he did it, only the dog knows. He could have been guarding his space under the chair, it could be a knee-jerk reaction to him seeing the girl as the bloke spooked him by quickly getting off the chair/guarding the man, it could be the smell of food that kicked in his guarding, he may of thought the little girl was suspicious, he may have problems with children from his earlier life
(what was he 're-habbed' for
?) etc... all guesse work. But what
didn't need guessing was the fact the dog was not happy with the girl and was prepared to act on it.
That poor little girl, how terrifying for her :(
