Ok, Carrie, duh...I just didn't put 2 and 2 together..I noticed that when I say hello to people, (in my usual, cheerful voice of course) Cody's very calm, stays in a down position, if on the porch, or just keeps on walking (or sniffing) with no reaction. Of course that makes perfect sense, no threat, everything's OK, I'm safe...Thanks again for the wake up call.
