Hacker The Dog, more commonly known as Hacker T. Dog, is a Border Terrier dog puppet who appears on the CBBC television channel in the UK. He is performed by puppeteer and guild member Phil Fletcher. Hacker was introduced as a character in the CBBC television programme Scoop, performed by Andy Heath. After the character became popular, Hacker was added as a weekday presenter at the CBBC office in May 2009, with the puppetry and voice now being performed by Phil Fletcher. Hacker from that point gained a much more noticeable characteristic, having a much more comedic and sarcastic personality and he now spoke in full words. In 2010, Hacker's "half-brother" Dodge T. Dog joined the presenting team on CBBC, while Hacker went off to film the second series of Scoop.The character took a hiatus from CBBC in April 2014 to film Series 4 of Hacker Time. During his absence, numerous guest presenters filled in for him during his usual weekday afternoon slot. Hacker returned temporarily on 24 May 2014, before making a permanent return on 18 June 2014.
