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.
In the spin-off media, K9 Mark II remained Romana's faithful companion for many years. In the early 2000s, John Leeson and Lalla Ward featured in a series of audio plays produced by BBV as K9 and "The Mistress", detailing these characters' adventures in a parallel universe. As neither Romana nor E-Space could be licensed, the aliases of the Mistress and the "pocket universe" were used instead.
K9 Mark I was created about the year 5000 by Professor Frederick Marius, who gave the dog to the Fourth Doctor and Leela. He was left behind with Leela on Gallifrey. (TV: The Invasion of Time) Some time later, he was blown up by a bomb on Gallifrey, (AUDIO: Imperiatrix) but survived. This model came to an end when Alistair Gryffen's Space-Time Manipulator randomly pulled him to London in the year 2050. There, he almost immediately self-destructed to protect Gryffen and a group of teenagers from Jixen warriors. (TV: Regeneration)
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 returned when Ship used the black hole as fuel. Though Sarah Jane, Luke, Rani and Clyde were happy to have K9 back, Mr Smith was not. (TV: The Mad Woman in the Attic) K9 spent a lot of his time in Sarah Jane's attic at 13 Bannerman Road, Ealing, but left to defeat Travast Polong. He attended Sarah Jane's abortive wedding to Peter Dalton, where he helped the Tenth Doctor, Luke, Rani and Clyde defeat the Trickster. (TV: The Wedding of Sarah Jane Smith) After helping defeat the Slitheen family, Clyde brought K9 to Park Vale Comprehensive School to help him with his test. He helped defeat the Rakweed before returning home. (TV: The Gift) K9 went to the University of Oxford with Luke, but restored Mr White's original programming through a mobile phone.(TV: Goodbye, Sarah Jane Smith)
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.
