Asking for advice on behalf of friends. They have a well behaved and generally calm 3 year old Doberman, Gracie. However when adults talk to each other or speak on the telephone the dog becomes very whiny and pestering for attention. Not so bad when in the house with just one adult, it seems to be worse when she's being ignored. If on the phone my friend puts her out of the room (so she can talk!) as Gracie is very loud and persistent. She then just whines on the other side of the door. Any advice on how to deal with this behaviour gratefully received.
