From what I've been told, jumped on first person aggressively, and second person tried to grab it off her and then bit that person's arm. She has a huge bite mark and is surprised she hasn't actually lost her arm.
I don't know what the law is for dogs that bite humans. It might be a case of being removed from the owners if it's not been trained properly? I don't think they're on the aggressive animals list - if they were and they aren't looked after properly, and they harm/bite a human, then I think they do get put down. I'm not 100% on that.
