Dog Trumpet or Reg & Peter's Dog Trumpet is an Australian rock band that was formed by brothers Reg Mombassa (aka Chris O'Doherty) and Peter O'Doherty. Both Mombassa and O'Doherty were members of the Australian band Mental as Anything, and they formed Dog Trumpet as an outlet for their material. The Dog Trumpet sound reflects affection for 1960s pop and psychedelia.
