Very nice video. I enjoyed it, thank you.
I have friends who have owned border collies, and unfortunately, the dogs had no one and nothing to herd. Both of them (they had one for years, and then another) were neurotic from lack of work.
My cousins have one. They brought it to Thanksgiving dinner, and as soon as it got into the house, where it had never been before, it went on a thorough scouting tour to get the layout and maybe check for danger. It is the most simpatico dog I have ever known. It seems to understand English.
