Thank you for the opinions, I agree with the majority of you. My niece has now admitted that she had hold of the dog's face and was kissing and cuddling it non stop for 1hr 15 mins before it obviously got p*ssed off and snapped at her. I now realise that of course it wasn't the dogs fault at all, I suppose I am quite naive about them and don't really know much about the breed apart from the bad reputation they have. They are keeping the dog anyway and the child is very very subdued and still upset about what happened, hopefully she has learnt her lesson.
