I went for a jog early this morning because I have to keep up with Jennifer Aniston who runs every day.  My face is still red from the heat which brings me to this question.  I passed another runner who had his dog on a leash.  The dog didn’t look so thrilled to be out on such a hot day.  Should I have said something or is it any of my business?  Someone told me that a dog would actually run itself to death to please its master.  Is that just an old wives tale?
