Hi - I've had my two babies for a month now and I have yet to hear a sound from them that I could positively identify as dooking. I have heard one make a sound, when he bounces around with his mouth open inviting play, that sounds more like a hiss with a semi-sharp throat sound at the end. Could that be dooking? If not, could someone post a specific description of dooking? Thank! -- ~W~ [Posted in FML issue 3152]
