The Littlest Hobo is a Canadian television series based upon a 1958 well-known film of the same name directed by Charles R. Rondeau.
It starred an ownerless intelligent German Shepherd dog, the titular Hobo, who befriends and helps humans (portrayed by notable Canadian and Hollywood actors in celebrity guest appearances).
Hobo encourages a paraplegic boy to enter a Frisbee-throwing contest to the dismay of the youth's overly-protective widowed father, who hates dogs because his driving at excessive speed and swerving to avoid a stray dog (who closely resembled Hobo) led to the car crash which killed his wife and left his son paralyzed.
Hobo helps a young boy prove to his mother that you don't have to play a rough sport like hockey to have courage.
When Hobo spots a disoriented woman, with amnesia, aimlessly wandering into a large amusement park (Canada's Wonderland), he finds his own way in and protects her from serious physical danger while alerting the security and bringing her medical help.
