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, 1995, RatDog became Bob Weir's primary band. They perform Grateful Dead tunes primarily with a mixture of covers (including Bob Dylan and Chuck Berry), along with some originals. RatDog's repertoire currently consists of over 150 songs.

Throughout 2009 and 2010, original RatDog members Bob Weir, Rob Wasserman, and Jay Lane periodically performed under the moniker Scaring the Children.
