[Vicky.]

Been thinking about this, how would it work if the house had a dog...and the dog bit the intruder. The dog doesn't know its the good guys, and the dog would not bite in any other situation than defending its home (to get rid of the 'dog shouldn't be vicious stuff that would usually reply to this...'). All the dog knows is that this person is not meant to be in the house when its parents aren't home...
