The video below is the result of our field test, conducted Tuesday evening.  Worth noting are the following observations:

— Not all headstones or areas attracted the dog.

—  When given the command to “search”, “find it”, or “find the people”, the dog appeared to understand what I was asking of her, moving towards headstones or areas as if in response.

— When moving towards groups of headstones, there were some that the dog looked at but would not approach.

Because I was alone with the dog at the location, I had to prevent her from pulling with one hand, and run the video camera with the other.  To provide reasonably viewable video, I was unable to film the areas where she seemed to see or hear things I could not.  I am hoping to find an assistant for future field tests.

Now, here is the video of field test #5.
