Eating ones best friend?

I'm starting to wonder if having a Dog shtf is a good idea, she's a great guard dog, if some one opens my gate and knocks at the door she won't bark, but if they touch the gate and don't knock or they just stand by the gate she will bark like mad, she won't bark no matter how much noise the neighbours make in their garden but, if they have visitors that she's not familiar with she will bark, she's very smart, but in a shtf situation if I wanted to stay hidden at home or bugout she would bark and give us away.
