Charlie would probably freak out because he's afraid of strange people. Jamie would probably bark since my in-laws' dog has taught her to bark any time anyone walks in the front door... (VERY annoying habit I've been trying so hard to get her to stop doing but they don't make it easy... she's a social barker!), so Jamie would probably start barking and then try licking them to death when they came inside... lol.

UNLESS they were wearing a ski mask or something of the sort; she is TERRIFIED of people in costume!!
