Although John Leeson has been the primary voice actor for K9 since his introduction, two other actors have voiced the character. David Brierley voiced K9 during Season 17 after Leeson chose not to return to the series (Leeson subsequently signed up again for Season 18), and Roy Skelton, better known for his work voicing Daleks, voiced the character in Destiny of the Daleks when all was required of K9 was a croaking sound due to the character contracting a form of robot laryngitis.
On 24 October 2015, Bob Baker and Paul Tams announced the film K9: TimeQuake which is destined for cinemas in 2017 and is to feature the robot dog facing off against classic Doctor Who villain Omega in deep space.

When Romana eventually returned to her own universe, she brought K9 Mark II with her (presumably having repaired it) and eventually became Lady President of Gallifrey. K9 Mark II is first seen on Gallifrey in the Virgin New Adventures novel Lungbarrow by Marc Platt, alongside K9 Mark I, which had remained with Leela. Both K9 Mark I and Mark II appear, voiced by Leeson, in the Big Finish Productions audio adventure Zagreus and the Gallifrey audio series. Leela's K9 (Mark I) was destroyed at the conclusion of the second Gallifrey series and only Mark II appears in the third series.

Jealous, Possessive by Paul Magrs, the "Scorpio" story in Big Finish's anthology Short Trips: Zodiac features K9 Mark I and Mark II relaying their exploits to each other, and their veiled put-downs to each other reveal that each considers the other to be the "inferior" version. This attitude is also occasionally hinted at in the way the two units refer to each other in the Gallifrey audio series.
K9 dogs are expected to perform well in various situations, such as finding a suspect through smell, protecting its handler, finding hidden objects in a 150’x150′ area, knowing how to respond when under fire, and detecting explosives and narcotics. Before a handler can start working with a dog as an official Police dog, the dog must pass the normative police test, or can be bought, fully prepared, from Master Dog Training.
When being imprisoned by the Sporraxx they tried to access K9's memory core. Memories that K9 had assumed to be erased were slowly coming back and the Sporraxx got to know more and more about K9's past. They reprogrammed K9 to protect a small spherical marauder bomb, that would destroy Earth. However K9 was able to break free of their control, because deep in his memories a sense of right and wrong prevailed. He took the bomb back into the Sporraxx space ship where it exploded. (COMIC: Short Circuit)
On 3 April 2010, the TV series K9 began broadcasting on the Australian Television Network Ten as part of a Saturday morning line-up of children's shows. John Leeson is the voice of K9. The first episode called "Regeneration"[13] featured the earlier Mark I version of K9. The "older" K9 materializes in London in the future and in the midst of an incident where an alien species is threatening human lives. K9 sacrifices himself in order to save the humans, but one component survives that enables his self-regeneration into the new unit. The main human cast members include Robert Moloney as Professor Gryffen, Keegan Joyce as Starkey (K9's new "master"), and Daniel Webber as Darius. The first 14 episodes of K9 season 1 were broadcast mid-morning on Channel 5 in December 2010 with the remaining episodes scheduled for January 2011. Trailers for the series appeared on Channel 5 from early December voiced by John Leeson. Originally, it had been planned to split the series in two halves between the Christmas 2010 and Easter 2011 school holiday schedules.

He usually did not engage in computer-like literal thinking, though on one occasion he followed Romana's instructions to "forget it" to the letter and erased all knowledge of tennis from his memory banks. (TV: The Stones of Blood) In another he took Romana's exclamation "Blast it!" as a command, and fired his blaster. (TV: Shada, WC: Shada, AUDIO: Shada, PROSE: Shada). Despite this, he occasionally showed a sense of humour, jokingly answering the question "What do you eat?" with "Ball bearings" (AUDIO: The Beast of Kravenos).
In 1996, Sarah used K9 to hack into records and find Sam Jones' home address and later to translate Lost Boy's speech. (PROSE: Interference - Book One) K9 was briefly possessed by a malevolent entity, but was freed when Sarah accidentally electrocuted him. (PROSE: The Sow in Rut) K9 began slowly breaking down and eventually ended up deactivated in a cardboard box in Sarah's attic. (PROSE: Moving On) Hilda Winters had K9 dismantled and analysed. (AUDIO: Mirror, Signal, Manoeuvre)
While caught up in a Time war between the past and the future on the planet Aoris, K9 was forced to spend a thousand years hidden on the planet, setting himself up as 'the great Machina' so that he could found a cult that would aid the Doctor and Romana in bringing the war to an end, hiding behind a fake computer with a version of the TARDIS until he could return to the Doctor and Romana once the war ended (AUDIO: The Paradox Planet, Legacy of Death).
Although John Leeson has been the primary voice actor for K9 since his introduction, two other actors have voiced the character. David Brierley voiced K9 during Season 17 after Leeson chose not to return to the series (Leeson subsequently signed up again for Season 18), and Roy Skelton, better known for his work voicing Daleks, voiced the character in Destiny of the Daleks when all was required of K9 was a croaking sound due to the character contracting a form of robot laryngitis.
K9 Mark I's mechanisms included rotating ear-probes, telescopic "eye" probe, an extendable nose concealing a powerful laser weapon, flashing lights on the top and the "eye" panel, waggling tail antennae, and ticker-tape tongue. His head could move up and down. His shell was painted in metallic gold/grey. There was a monitor screen on his left flank, though K9 rarely used this during his travels with the Doctor. Around K9's neck was a tartan collar, (being the Family Tartan of the Clan Buchanonn) from which hung a silver disk. (TV: The Invisible Enemy) He was later modified to fly through the vacuum of space. (TV: Curse of Anubis)
When the Tenth Doctor created K9 Mark IV to replace K9 Mark III, he added a shiny metallic blue paint job and other improvements, including an omniflexible hyperlink facility. (TV: School Reunion) Later, though, K9 reverted to his old dark green colour. (TV: Invasion of the Bane) In battling Mr Smith (and following the battle) K9 displayed a teleport facility and a laser weapon similar to the previous K9s'. (TV: The Lost Boy)
K9 Mark 2 was the result of the activation of the Mark I's onboard regeneration unit. He had only very limited memories of his past as the Mark I. He had many adventures with Alistair Gryffen, Jorjie Turner, Darius Pike and his new master Starkey. (TV: Regeneration, The Bounty Hunter) Orthrus was an attempt by Drake and the Department to replicate K9, but it was of vastly inferior design. (TV: Jaws of Orthrus)

I use K9 to keep my kids out of offensive web sites especially adult and bad reputation sites. I also like the new "Advanced YouTube Filtering" which seems to be working okay. Now my 11yo daughter can use youtube, which I previously had it blocked. If your kids are old enough talk to them, tell them internet is like a car, it's a great tool, you can use it to go to good places and bad places, so it must be used with responsibility.

K9 was a popular enough character to warrant an attempt to spin him off into his own series. In addition to K9 dolls, there were also talking K9 toys produced by Palitoy, the speech provided by a miniature record inside the body of the toy. John Leeson provided the voice for K9 in all its appearances, except for Season 17 (which included the unfinished Shada) when it was voiced by David Brierley. When Shada was remade by Big Finish Productions, Leeson provided its voice.
