The Littlest Hobo

The German Shepherd dogs featured in both 1960s and 1980s series were owned and trained by Chuck Eisenmann. The primary star was named London, but several of London's relatives, including Toro, Litlon, and Thorn, also played scenes as the Hobo. Eisenmann used his own training methods to work with his dogs which involved educating them to think and understand very specific directions, to recognize colours, and to understand English, German, and French.^[2] He promoted his education method by touring with his dogs to offer live demonstrations,^[3] appearing on TV and radio shows and by writing books.^[4] Eisenmann recounts many stories from the filming of the series in his 1968 dog training book Stop! Sit! and Think. Other books he wrote include The Better Dog: The Educated Dog which contains updated training material and A Dog’s Day in Court which offers a dog's point of view towards training methods.

The dogs have "reverse mask" markings. After purchasing London, Eisenmann began to breed his own dogs, mostly studding out his males, even though he owned some females that he bred to as well. He bred particularly for the reverse mask, that is commonly seen on all of his dogs, and is unpopular with breeders of the German Shepherd, as it is not in the breed standard.

Shiloh Shepherd dogs are stated to trace their heritage back to London's relatives and are inspired by the intelligence Eisenmann's dogs were reputed to have.^[5]

The concept was well-suited for series television offering a variety of different settings for a road program, with an undemanding "star" and new slate of supporting human players every week. Some notable Hollywood guest stars included Pat Harrington Jr., Nita Talbot, Ellen Corby, Henry Gibson, and Keenan Wynn (the last two of which would also guest-star in the 1979–1985 revival series).

In 1979 CTV revived the series. The New Littlest Hobo (as it was sometimes called), which ran for six seasons, was shot on videotape rather than film. It has since been syndicated in many countries including the US and United Kingdom. In the course of its run, a mixture of well-known Canadian and Hollywood guest stars appeared such as Al Waxman, Carol Lynley, John Ireland, Megan Follows, Rex Hagon, Alan Hale Jr., Jack Gilford, August Schellenberg, DeForest Kelley, Ray Walston, Morey Amsterdam, Jeff Wincott, Michael Wincott, Michael Ironside, Patrick Macnee, Abe Vigoda, Saul Rubinek, John Vernon, Keenan Wynn (who also previously appeared in the original 1963–1965 series), Chris Makepeace, Karen Kain, Vic Morrow, Andrew Prine, Lynda Day George, Nerene Virgin, Tedde Moore, Sammy Snyders, Henry Gibson (who also previously appeared in the original 1963–1965 series), John Carradine, Leslie Nielsen, Anne Francis, Geraint Wyn Davies, and Jayne Eastwood. Mike Myers appears as Tommy in episode 10 "Boy on Wheels".

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.

In a nod to the original series, the dog that appeared in this series was also credited as "London".

Plots ranged from the simple "dog-helps-person" stories to secret agent-type adventures.

In two-part, fifth-season 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. 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. At the end of the episode, Hobo found the evidence the reporter and scientist had collected and destroyed it, implying that Hobo did not want any evidence of his origins or nature becoming public.

Trainer Eisenmann used several dogs to play the role of "London" as he had selected dogs entirely based on their appearance. He determined which dogs to use for the scenes by making use of their abilities such as if one dog did not mind carrying objects or if one were small enough to safely jump through a car window and manoeuvre through the seats. In Eisenmann's book, A Dog's Day in Court, one of the dogs used in the 1970s series was London's grandson, who was also known as London.

A 2005 episode of the CTV sitcom Corner Gas, entitled "The Littlest Yarbo", pays tribute to the series by having a character (Hank Yarbo) convinced that a stray dog visiting the town is Hobo. The episode ends with a reprise of Terry Bush's "Maybe Tomorrow" theme song.

The series' theme, "Maybe Tomorrow", was written by Terry Bush and John Crossen. The original was sung by Terry Bush. In 2005, Bush commercially released the song on his debut album, entitled Maybe Tomorrow.^[6] A NatWest advertisement promoting its credit card services featured the song, accompanied by animation of a dog wearing a NatWest credit card on its collar. The song was later used in a 2011 Dulux paint advertisement.^[7] Additionally, in 2017, the song was in a Canada 150-themed Co-Op stores advertisement.^[8]

Following the 1958 film, the 1960s original TV series was aired in syndication around the world, including the United Kingdom on ITV, Australia on the Nine Network between 1964 and 1967 and New Zealand on TV One. Although the series was originally telecast in black and white, it was produced in colour. The VCI Entertainment DVD release of the series featured the colour versions of the episodes, except for the opening and closing credits which have only recovered in black and white. Sixty-one episodes were broadcast over two seasons.

Storer Programs Incorporated, a unit of the now-defunct Storer Broadcasting, distributed the series to U.S. television stations during its 1960s run.

VCI Entertainment has released 12 episodes from the original series to DVD. The release features the colour versions of the first three episodes, except for the opening and closing sequences which have only recovered in monochrome. The last 9 episodes were released in black and white.^[9]

The series aired on CTV on Thursday nights at 7:30 p.m. Repeats continued on CTV, CTV 2, and other national networks up until 2012, when CTV replaced it with a block of music videos from Juicebox. However, CTV2 recently resumed repeats of the 1980s incarnation. It aired in the US in syndication during its original run. In the United Kingdom, the series premiered on the BBC on April 8, 1982, but only the first three seasons were 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.

Mediumrare Entertainment have only released the first two seasons of The Littlest Hobo on DVD. The Season One DVD, featured the theme tune "Maybe Tomorrow" on DVD in Region 2 & 4 on April 26, 2010.

In 2017, episodes from the series started to be uploaded onto Encore+, a YouTube channel run by the Canada Media Fund and Google Play in Canada.^[10][11] The episodes have since been removed from the channel. As of 2023, the entire series is available on CTV's website through the "CTV Throwback" lineup, and repeats came back on Bell Media's channels: CTV, CTV 2, and Animal Planet.
