Disco Dogs were the final act to audition for Series 13 of Britain's Got Talent. The group consisted of presenters Ant & Dec and co-presenter Stephen Mulhern, however this was not revealed until the end of the act. Instead, when asked questions at the start of their audition, they did not respond.
Their audition began with the trio performing to 'Hound Dog' by Elvis Presley, before switching to 'Gangnam Style' by PSY, later switching to ‘Who Let The Dogs Out’ by Baha Men. At which point beach balls were released into the audience, and the Judges were given dog outfits to wear during the performance. David described the act as 'Completely bonkers, and completely [BGT], whilst Simon stated that the act was 'A great end to the show this year'. After being sent through to the next round, the trio pulled, their masks off, revealing themselves as the Britain's Got Talent presenters. Ant then remarked 'We've finally done it, we finally got through the Britains Got Talent auditions’. They did not progress through to the Semi-Finals.
