It may well be that my baby boomer memory is having a seniors moment but I feel certain that our main character was not a German shepherd but some other sort of canine of approximately the same dimensions. Maybe someone else with a better memory might be able to enlighten us. All I can say that I still get a warm glow inside whenever I think of this wonderful children's show. Each episode was a vignette of new characters to which our Hobo usually helped resolve a human dilemma with animal heart. So sad to think the world that could create such wonderful things with so much love is gone forever... and yet it left such a lasting impression on this 50yo man...
