What is "ratdog"

RatDog (sometimes known as The Ratdog Revue, Bob Weir & RatDog or Ratdog) is an American rock band. The group began as a side project for Grateful Dead rhythm guitarist Bob Weir and bassist Rob Wasserman. After the Grateful Dead disbanded in December 1995 following the death of Jerry Garcia on August 9 of that year, RatDog became Bob Weir's primary band. The band performed until July, 2014. They performed Grateful Dead tunes primarily with a mixture of covers (including Bob Dylan and Chuck Berry songs), along with some originals. RatDog's repertoire consisted of more than 150 songs.
