Do you think maybe he was being vocal because he was scared. Not scared of your daughter but just caught off guard. You know how someone walks up behind you and scares you and you either scream or at least make a loud noise. Maybe that's what he was doing and it took a minute for him to realize that it was a member of his family. Of course I'm no expert but that's just my opinion.
My little puppy does this when he is caught off guard.
