<P> Charles (Chuck) P. Eisenmann appeared as a dog trainer named Chuck in the first - season episode "Stand In" and as dog kennel operator named Mr. Charles in part one of the episode "Voyageurs" from the sixth season . </P> <P> The series aired on CTV on Thursday nights at 7: 30 p.m. Reruns continued on CTV, CTV Two and other national networks up until the early 2010s, when CTV replaced it with a block of music videos from Juicebox . In the UK the series premièred on the BBC on April 8, 1982, but only the first three series was shown and repeated until 1989 . From April 1991 ITV picked up the series and each of the local companies played out the full series until late 1994 . </P> <P> Plots ranged from the simple "dog - helps - person" stories to secret agent - type adventures . The series theme song, "Maybe Tomorrow", was sung by Terry Bush . In 2005, Bush commercially released the song on his debut album, entitled Maybe Tomorrow . The song was later used in a 2011 Dulux paint advertisement . Additionally, in 2017, the song was in a Canada 150 Co-Op stores advertisement . </P> <P> In season 5's two - part episode "The Genesis Tapes" a scientist and a reporter theorized that Hobo was a type of superior canine . The reporter theorized that there was one dog and the scientist theorized that there were up to one hundred such dogs . The two part episode had the scientist and reporter trying to capture Hobo to study him, with the reporter wanting a story and the scientist wanting to claim to be the first to discover the meta - canine as he put it . Hobo succeeds in destroying VHS tapes of himself that the scientist and reporter had intended to use to prove that he was an evolved canine . Both episodes feature flashback footage from the first five seasons of the series, with the first episode being the only episode of the revival series to include footage from the original 1960s series . The episode does not confirm that Hobo was indeed a superior canine either by evolution or design; it was simply the theory of the scientist and reporter . </P>
