Black Dog is the fourth solo studio album (fifth overall) by English electronic music project Gazelle Twin of composer, producer, and musician Elizabeth Bernholz.

[1] Bernholz herself thought Black Dog was the "rawest thing" she had ever made, soon realising that she was not writing "about ghosts" but her own "mental state".

[3] Spyros Stasis of PopMatters called Black Dog the sum of Gazelle Twin's "past strange adventures" that also "forges a new path" for the musician.

[7] Writing for The Quietus, Lottie Brazier named Black Dog their album of the week, calling it a record of "disarming vocal force" influenced by "childhood nightmares and uncanny reminders".

[5] Likewise, the editors at Mojo applauded Gazelle Twin for including "evocative sonic components" that slowly ceases halfway through the album but does not affect the "overall consistency".
