Dog's Blood is a collection of four experimental songs that are different-sounding from the band's previously released material.

Work on the Dog's Blood EP was originally announced in September 2009, shortly after the release of Old Crows/Young Cardinals in July 2009.

[11] Though much of the EP was written by September 2009, the band's busy touring schedule delayed recording of Dog's Blood until mid-late 2010.

[12] All of the tracks on Dog's Blood are songs that the band members felt were too different from their other material to be included on a full-length album.

[7] Dog's Blood was released through Dine Alone Records on November 23, 2010, though it was distributed internationally on various dates through different labels and also through online music retailers.
