Charlie Brown and the Peanuts crew have delighted fans for more than half a century. But what happens when those innocent kids become teenagers? In the play “Dog Sees God: Confessions of a Teenage Blockhead,” Linus is a pothead, Snoopy is dead, Lucy is imprisoned and Pigpen is a germaphobe. Good grief! Raleigh Ensemble Players will be performing “Dogs Sees God,” which follows the Peanuts gang in high school as they deal with the drama and turbulence of the teen years.
