More Information : K9, is the name of several fictional robotic dogs in the long-running British science fiction series, Doctor Who, and its spin-off series, The Sarah Jane Adventures. There have been at least four separate K-9 units in the series, with the first two being Companions of the Fourth Doctor. Voice actor John Leeson has provided the character's voice in most of its appearances, except during Season 17, when David Brierly temporarily provided the voice.
A new television series starring K-9, K-9 Adventures, is currently in development and is planned to air in 2008.

All the K-9s referred to whoever owned them as "Master" or "Mistress" depending on their gender. The units were programmed to be both loyal and logical, with a penchant for taking orders literally, almost to a fault. The Fourth Doctor would often use a glib remark to disarm those who were surprised by K-9's appearance; in The Stones Of Blood he said, "They're all the rage in Trenton, New Jersey." The Tenth Doctor defended its less-than-streamlined design ("...so disco!") to Rose Tyler, remarking that it was cutting edge in the year 5000.

Next Appearance : K9 Adventures Or Sarah Jane Adventures
