Sabi and I were doing a patrol of the old base, we were checking what used to be the old base commanders house? I think. She was loose as she was not yet certified for patrol and we were on a closed facility, so really just keeping me company. She suddenly darted forward, barking and growling like crazy, stopped dead and cowered like someone had hit her, yelped and high tailed it back to hide behind mom. The houses had floodlights all over them, there was absolutely nothing there. We finished the patrol, but her hackles stayed up until we were back in the truck. Hundreds of patrols after that never produced that response again.
The old mess hall however was a different story. For all the years we spent checking that building, Sabi stayed at the end of her leash, as far from that building as she could get and no amount of bribing, corrections or threats would convince her to set foot inside. Not any other pup or dog we ever had would go near the place either. We commonly let the dogs loose after the gates were shut and not one dog would go there. Since we used the base for training every patrol dog did time there and the other buildings never posed an issue. We ran set ups in the hangars, dorms, shops and offices but the mess hall was never used because even if we forced the dogs inside, they were useless.
The old boy that built our house passed away just before we moved in, at 101 years old. I am convinced that Shadow sees him, and likes him. We found a room under the stairs hidden behind an old cabinet full of old bottles of liquor and an ashtray with a cigar stub in it. Shadow is fascinated by it and runs to it wagging her tail and scratching at the hidden entrance. If I let her in she dances around with her tail wagging, just like she's greeting someone she knows.
