K9 was a spin-off television series featuring the robotic dog K9. It was produced in Australia by Park Entertainment and Stewart & Wall Entertainment under the auspices of Metal Mutt Productions, a business identity of Bob Baker which holds primary copyright to the series. K9 premiered worldwide between 2009 and 2010. In the wake of the first series, there were indications that a second series was being planned. In June of 2012 series producer Paul Tams stated that he and Bob Baker were "working on the updates for series two and also entering a new production partnership." with another twenty-six episodes planned. They also claimed to have adjusted the K9 CGI model based on the positive and negative comments from fans. Test footage had apparently already been filmed, with further announcements regarding production supposedly due later in 2012. The new design of K9 was to be unveiled at a convention in 2013. However, this never came to fruition and only vague reassurances about the progress of the second season came from Baker & Tams in 2014. The Essential Book of K9 was then released in 2015, including a trilogy of short stories about the further adventures of K9 Mark 2, set long after the end of this television series and distancing him completely from it. A comic story was also included which finally revealed the new design of K9.
School Reunion led to near-immediate plans to launch the Sarah Jane Adventures spin-off. The rights to K9 were obtained by other parties for a separate spinoff. According to news reports in mid-2007, the K9 series would "feature a blend of live-action and CGI: K9 himself will be a CGI creation, but the show will otherwise be recorded in front of cameras." In June 2008 it was announced production would begin on the series in July 2008, with all or some of the episodes written by the co-creator of K9, Bob Baker. Other announced writers included Shane Krause and Shayne Armstrong. The series would be produced by Simon Barnes, Richard Stewart and Penny Wall. Due to licensing issues, the robot dog was extensively redesigned. At first, the series was not expected to have any obvious connection to the Doctor Who universe., but a 2009 update to the Park Entertainment website revealed that the series would explicitly star K9 Mark I and he would initially appear to be the same design seen on Doctor Who. These licensing issues also prevented K9 Mark IV from initially making more than cameo appearances in The Sarah Jane Adventures. K9 later became a regular for series 3 of SJA.
K9 was the first Doctor Who-related series to not be produced or co-produced by the BBC. It marked only the second time, after the 1996 Doctor Who TV Movie, that an official Doctor Who-related production was not based in Great Britain.
The first season of the series consisted of twenty-six episodes of thirty minutes each, which gave it a similar run time to an average series of Doctor Who. It was the first time a Doctor Who-related season had so many episodes since Season 19 of Doctor Who.
The first episode of the series premiered in the UK on the cable network Disney XD as a special on 31 October 2009. The series began airing as a weekly offering on a Scandinavian network in January 2010. It commenced broadcast in the UK on 3rd April 2010, the same day it premiered on the Ten Network in Australia. This was also the same day that Series 5 of the parent program debuted in the UK. Nevertheless, the later December 2010 broadcast on Five was claimed to be the "premiere" UK broadcast. Currently, Disney XD has adopted a twice-weekly broadcast schedule for K9, airing episodes on Saturday and Sunday.
