The dog that is trapped in the body of a Rottweiler (she genuinely is a Labrador, for sure) still does not do the duties she's supposed to do (barking, biting, guarding, fighting, defending,...) so like usual I have to help myself.

I organized a 2 kg ship bell and mounted it to the post at the gate. So far so good. But how to train an Australian native to use this bell? To make clear not to come to my house and look through my kitchen window so that I'm scared to death? Those natives (workers, neighbours even deputies of the council) are just entering the property, ignoring the "guard dog" and going to the back of the dwelling. Oh I hate this habit. I know where it comes from: when entering an Australian house you are standing in the living room. Very often there is no corridor or entrance hall and so they go to the back where the tiled laundry is. When I'm lucky they give me a call - like yesterday when the builder of my decking arrived. He knows my mobile number. The guy is standing at the gate, next to the bell, Clare in front of him wagging her tail and he is calling me by phone that he wants to enter.
Now I printed a sign - hopefully they are able to read (the guy from the electricity is announced to come in the next couple of days to do the meter reading - I'm waiting in suspense).
