Series 1 (K9)

Series 1 of K9 premiered in full in 2010 with a run of 26 30-minute episodes in the series -- the longest Doctor Who-related season since Season 19 in 1981, which also had 26 episodes. It is also the first full-season production of a non-BBC-produced spin-off series, and is also the first franchise season to be wholly produced outside the UK, as it was produced and filmed entirely in Australia.

The first episode aired on Disney XD (formerly Jetix) in the UK as a special on 31 October 2009. This was followed by the series in full premiering in Scandinavia in January 2010; most episodes, therefore, had their world premiere months before Australia or the UK. The series debuted in full on Disney XD in the UK and in Australia on Ten on 3 April 2010, only hours before the start of Doctor Who Series 5 in Britain.

As with its parent program, K9 series 1 used individual episode titles for both standalones and multi-part storylines. Two multi-parters were in this series, an initial three-part story leading off the season, and a five-chapter story concluding it.

Merchandise
The Complete Book of K-9, a piece of non-fiction following the story of K-9 through all four models, crossing over from Doctor Who, K9 and Company, The Sarah Jane Adventures and of course K-9 itself was advertised. But as of early 2015 it hasn't been released. A tie-in called The K-9 Storybook was going to be released in 2011 containing behind-the-scenes extras, short stories, comic strips and other material from the live-action series, but in early 2015 it still hadn't been released. Instead the The Essential Book of K9 was introduced. It included K9's complete story of Doctor Who, special features, exclusive photos, stories and comic strips from some classic names including Bob Baker. It was released in July 2015. Finally there is one K-9 Mark 2 figurine ready for sale.
