Dog Trumpet, originally known as Reg & Peter's Dog Trumpet, is an Australian rock band, founded in 1990 by brothers Reg Mombassa (aka Chris O'Doherty) and Peter O'Doherty, original members of Australian new wave and pop rock band Mental As Anything.

Under the name of Reg & Peter, the duo issued the single "Jean"/"Nobody Home" in March 1991 on Regular Records, the song is described by Mombassa as "a fusion of psychedelic and Celtic rock 'n 'roll dealing with metaphysical romance", before assuming the name Reg & Peter's Dog Trumpet for the album Two Heads One Brain.

Two further singles were lifted from the album, "Made of Wood"/"Red Brick Home" in June 1991 (the cover art for which is a painting of a howling dog trumpet by Mombassa) and "I'm So Handsome"/"Dream" in October 1991.

The artwork for Strange Brew, was painted by Martin Sharp, who designed several album covers for the real Cream in the late 1960s.

Dog Trumpet released their fourth album Antisocial Tendencies in March 2007 on Half A Cow Records.

Dog Trumpet's seventh album, Great South Road, was released in May 2020 and featured the singles "Gravity", "Wallpaper", "Lonely Death Cleaning Company", "You've Heard it All Before" and "Overseas and Elsewhere".

"The Ballad of Clayton Looby" on 9 September 2022, from their forthcoming album, Shadowland, which is scheduled to be released on 4 November 2022, on vinyl, CD and digitally worldwide by the Demon Music Group.

Little did we know we’d still be together today.”  - Peter O’Doherty[citation needed]Shadowland is a distinctive blending of psychedelia, folk and blues, the album probes the perils and absurdities of human existence, kicking off with the title track "Shadowland", a nervous musing on digital over-surveillance; followed by "Nina Simone", a song reflecting on romance and memory.

"F***ing Idiots points" out the shameful idiocy of our addiction to war and militarism; "The Ballad of Clayton Looby" is an anti-establishment ode to a larrikin surfer.

While she was touring Australia in 1996 Reg and I met her at a party in Sydney at artist Martin Sharp’s house where she told us how much the song meant to her.

Recently Dog Trumpet started playing Marianne at gigs and we decided to re-record it with a new approach and sound and updated lyrics.
