My home is 2 stories, with the bedrooms all upstairs.
As a family, we have talked about what to do in the event of various emergencies. If someone were to break in, my wife is to arm herself, gather the kids ( only one left at home and she is 21) in the bedroom, and call 911. I will take a position in the bathroom at the top of the stairs.
Perp can leave with whatever he wants, I will not engage, but there is no way he is coming up those stairs.
I don't care if he leaves with the TV, silverware, electronics, whatever.
The wife also has explicit instructions to tell the 911 dispatcher to please refrain from shooting the white guy in his underwear and the Black Labrador Retriever.
But it is pretty unlikely a common burglar would try to enter a house with a barking dog, going ballistic.
