srnity: Was it a German shephard I had one that did that and had to turn all the door handles upside down and they are still upside down about 15 years later! And I just rememberd, this was when I was living at my mam,s and if I was carrying two plates into the dinning room and the door was shut, I just had to say open the door" and she would. She did not like strangers though and we turned the handles upside down to stop her getting in if anyone else was there but of course she could push them up as well as down.
