RatDog (sometimes known as The Ratdog Revue, Bob Weir & RatDog or Ratdog) was 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, and Weir has not ruled out future shows. 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.
Throughout 2009 and 2010, original RatDog members Bob Weir, Rob Wasserman and Jay Lane periodically performed under the moniker Scaring the Children.
From 2010 through 2013, the number of RatDog's performances were limited while Weir toured with Furthur. Ratdog played 2 shows in both January 2012 and August 2013. In September 2013 it was revealed by Primus bassist Les Claypool that RatDog would be "getting back together this next year", as Lane had chosen to leave Primus in order to rejoin RatDog.
