I ran a search of "Wolf Dog" actor Juan Root on Google and to my shock and surprise, up came this link to an interview of TCA (Trans Canada Airlines) pilot Frank Young. Root was listed as "reporter" for this May 2, 1957 broadcast. now in the CBC Digital Archives.
     The program was called "Assignment" and was hosted this day by Bill McNeill and Maria Barrett. Enjoy! If you learn of any such tidbit of a "Wolf Dog" actor, pass it along and I'll post it on this website! Thanks!
