Dust-obscured galaxies (DOGs) represent a recently-discovered, intriguing class of mid-IR luminous sources at high redshifts. Evidence is mounting that DOGs (selected on the basis of extreme optical/mid-IR color cut and high mid-IR flux level) may represent systems caught in the process of host galaxy formation and intense SMBH growth. Here we report the results of an X-ray spectroscopic survey aimed at studying the X-ray properties of these sources and establishing the fraction of Type 2 quasars among them.
