"Blue Dog membership was nearly cut in half by the 2010 Election, in which 26 members were re-elected but 28 were either defeated or chose not to run for re-election.
The membership is expected to decline further in the 113th Congress. Membership is already down to 25 with the resignation of Jane Harman, one of their more liberal members. Furthermore, four prominent remaining Blue Dogs, Dennis Cardoza of California, Dan Boren of Oklahoma, Mike Ross of Arkansas, and Heath Shuler of North Carolina have announced their retirement; one member, Joe Donnelly of Indiana, is running for Senate (partially due to Republican redistricting efforts); and more members, such as North Carolina's Mike McIntyre as well as Georgia's John Barrow, have been or will be targeted by Republicans in redistricting efforts.[23] Additionally, the group is likely to shrink further with the defeat of Jason Altmire and Tim Holden in the 2012 Pennsylvania primary by more liberal politicians.[24]
Freshman Blue Dogs in the House are sometimes nicknamed "Blue Pups".[5]"
