Despite its weak ratings (see “Dollhouse Premieres Weak”), Fox will air all 13 episodes of its current order for Joss Whedon's Dollhouse, according to Hollywood Reporter.  One reason is that DVR viewers boosted the premiere week rating by a full 50% when seven-day viewing is included, the top percentage boost for premiere shows (tying with Smallville).  Last Friday’s episode also bounced back after a second-week drop, matching its viewers for the premiere week. 

Fox says it will make a decision about continuing the show after all thirteen episodes have aired.
