Dr. Dog is a rock band from West Grove, Pennsylvania. Its lineup consists of Toby Leaman (bass guitar), Scott McMicken (lead guitar), Frank McElroy (rhythm guitar), Zach Miller (keyboard), Eric Slick (drums), and Dimitri Manos [Multi-instrument]. Lead vocal duties are shared between Leaman and McMicken, with all members contributing harmonies. In addition, each band member has a nickname beginning with the letter T, and they have explained that friends of the band also receive nicknames, which are drawn from aspects of their lives and personalities (Former member Andrew "Trial" Jones, for example, is a licensed attorney).

The band's unique version of indie rock is strongly influenced by bands of the 1960s, such as The Beatles and The Beach Boys, but they have also touched upon more unrelated genres since their inception. Their earlier recordings show influence of the lo-fi sound and pop sensibilities of indie rock bands of the 1990s, such as Guided by Voices and Pavement, although recent albums have featured more polished production.
