"Hey Bulldog" is a song by the English rock band the Beatles released on their 1969 soundtrack album Yellow Submarine.

[4][5] Demo recordings made in the winter of 1967–68 at his Kenwood estate in Weybridge include the melody that later became the song's chorus, as well as a section working out the "she can talk to me" passage.

[19] Lennon suggested his half-completed idea "Hey Bullfrog",[4] which he and Paul McCartney finished while in the studio.

[23] As the band neared the end of the basic track for "Hey Bulldog", McCartney attempted to make Lennon laugh by barking like a dog.

[21][note 1] Lennon changed the song's name to "Hey Bulldog",[4] though the title phrase does not appear until the outro.

[19] The camera crew left as the band continued working on the song with various overdubs onto take ten,[23] including off-beat drums from Ringo Starr, a distorted Gibson SG from George Harrison for the song's intro, double tracked vocals from Lennon and a harmony vocal from McCartney.

[23] Apple released Yellow Submarine in the US on 13 January 1969, with "Hey Bulldog" sequenced as the fourth track, between "All Together Now" and "It's All Too Much".

It was cut from the American version by the movie's producer Al Brodax as he and the group felt the film was too long.

[32] According to Walter Everett,[4] except where noted: In 2018, the music staff of Time Out London ranked "Hey Bulldog" at number 28 on their list of the best Beatles songs.
