Ok, so I know it's not helpful at all, but the fact that you said dog/child cracks me up. Every time I read any of the responses in my head I subsituted the word "dog" for "dog/child" and giggled to myself. They can't be serious, right?!?!
PS...I think it's a little odd that anyone would bring their pet to another person's house unless 1) they were out on a walk and just stopped by for a chat on their way or 2) the homeowner REQUESTED it.
