Every day, Red walks into the barn and stands where Rocky needs to go. For the blind pony, the topography is different, as you can see. He has to make it past some new poles and Red walks a few feet in front of him, and stands and waits, and Rocky sniffs and walks up slowly, until he smells or senses Red and moves forward. None of this is done with any training – a pony and a dog communicating with one another in ways that are beyond me but which are mesmerizing to watch.
