For a majority of their career, the band's line-up has consisted of lead vocalist Jemina Pearl, guitarist Jonas Stein, bassist Nathan Vasquez and drummer John Eatherly.

Shortly following the release of their second album Get Awkward in 2008, the group disbanded, citing misogyny directed towards and experienced by Pearl and a general burnout from pressures of the music industry as the reasons for their split.

[2] They subsequently signed to Third Man Records (co-owned by White and Pearl's husband, Ben Swank) soon after, where the group released their third studio album, Mommy on August 25, 2023.

In a 10-year retrospective article for the film Scott Pilgrim vs. the World, director Edgar Wright revealed that Be Your Own Pet was originally asked to write the music for the fictional band Sex Bob-Omb, but their breakup prevented this from happening.

The album was co-written with Eatherly, and featured guest appearances from Thurston Moore, Iggy Pop, Dave Sitek and Derek Stanton.

[6] In March 2022, Be Your Own Pet announced they would be reuniting to perform two concerts in April 2022 opening for Jack White's Supply Chain Issues Tour.
