Hello!  My husband and I adopted a 9-month-old Caucasian Ovcharka yesterday and already LOVE her!  However, she paws at the door incessantly when we put her out in the backyard for any length of time, even a matter of seconds.  I know not to open the door and reinforce this behavior, but how can we stop it?  I know she probably just wants to be with us, but that's not possible 24/7.  We don't want her to hurt herself and avoiding damage to the door would be nice, too.  Suggestions?
