I know it has been a while. Hope you are well. I hope you are still helping out or can forward this to them. Received the above link from another rescue group. Thought you might want to forward it to the other people on your messaging list.

Sable is now queen of the house. She knows her boundaries and runs for the fence when a stranger comes up the driveway. To explain, the fence closes off 45% of the yard sides, neighbor’s house does about 20%, another fence does 25%, driveway makes up the other 10%, driveway is open to the road.  There is a motion detector across the driveway, and she know that is her boundary.
