Zoee would probably bark for a few seconds and if/when the burglar talked to her she'd do her butt waggle and be all excited. This is what she does with people when we ARE home.
Although, I have no idea how she'd react if we weren't home. I've been tempted to have someone she has never met come into the house while we are away and see what she would do.
Ohhh, I know!! We are going to have a co-worker of mine power wash our deck. I should test it then.
