I have a good friend who does this for me all the time. One time, I'd lost my cell phone. She told me it was in a 'dark place, near my back door'. I searched all over that room, and finally found it under the sofa.
She's directed me to countless 'lost things'.
Red Willow, if your dog is still missing let me know. I'll ask her for you to see if she picks up anything.
